I deployed an XBAP application on two different servers with different domain names. Unfortunately, It loads ok on first browsing domain and throws the exception below when browsing second. If I use mage -cc to clear the cache, again, it loads fine on first browsing domain and throws exception on second.
ERROR SUMMARY Below is a summary of the errors, details of these
errors are listed later in the log. An exception occurred while
downloading the application. Following failure messages were detected:
Unable to install this application because an application with the
same identity is already installed. To install this application,
either modify the manifest version for this application or uninstall
the preexisting application.
In the Manifest file, change the version of the application identity or republish, check in the project properties ->publish->check automatically increment revision with each publish. Then publish it and then run it.

ASP.NET Core 2.1
We have a shared dll, that is used in a few projects (via project reference)
We have class in that was named Proofer, and is now named ProofReader.
This was done through mass find and replace.
Nowhere in our source files locally exists any files containing the text Proofer.
VSTS builds the application without issue, then we send it via a release pipeline to Azure. All succeed.
Despite this we attempt to run the web app and get the following:
An unhandled exception occurred while processing the request.
TypeLoadException: Could not load type
'MainShared.Models.Proofer' from assembly 'MainShared,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
System.Reflection.CustomAttribute._CreateCaObject(RuntimeModule
pModule, IRuntimeMethodInfo pCtor, Byte** ppBlob, Byte* pEndBlob,
Int32* pcNamedArgs)
We are having trouble determining if this is in the build, maybe something not being rebuilt when it should be, or something still cached on Azure that isn't being overwritten.
A few places I can suggest you look into -
If you are using app service web apps in azure , we can use the kudu (web app extension to remove/clean the files) to make sure you have a clean destination.
Check the VSTS Release logs if you have access to , it shows the files which are overwritten and the ones which could not be. Once i had a similar issue and found that the logs were already warning me that a few could not be overwritten.
If you are using VM's for your app deployment if has access to it , remove/backup the files under your site folder.
I had a similar problem after some redesign for a Web App using ASP.NET Core 2.2 (hosted on Azure), that some old not even anymore existing references causing the Load type exceptions to happen and the Web App simply refused to come up. I tried to clean everything up in Visual Studio, even deleted the bin and object directories, but the old reference was still looked for. In Kudu on the Azure portal I saw the *.PrecompiledViews.dll and *.PrecompiledViews.pdb files, which were very old. I simply removed them directly on the Azure server and could then simply start up my app and everything came up again. This fault should be fixed from the source. If I do a complete rebuild, I expect this old garbage to be taken care of during the publishing to the website. This is something that Microsoft should fix and as I can see this happened to others over half a year ago. Thanks Mark Johnson for your very useful hint about those files!
I'm currently in the process of migrating an ASP platform from Windows 2003 R2 IIS 6 web servers to Windows 2012 R2 IIS 8.5 web servers. I'm at the stage where I've migrated a number of sites across to two separate 2012 web servers, all looked great, clients and developers are happy... However the following error has presented itself after a few days hosting on one of the new servers.
Active Server Pages error 'ASP 0223'
TypeLib Not Found
/jobboard/conf/constants.vbs.inc, line 1
METADATA tag contains a Type Library specification that does not match any Registry entry.
The METADATA tag is below:
<!--METADATA TYPE="typelib" NAME="Microsoft ActiveX Data Objects 2.8 Library" UUID="{2A75196C-D9EB-4129-B803-931327F72D5C}" VERSION="2.8"-->
Restarting IIS on this server resolved the issue (albeit temporarily).
Subsequently the other 2012 web server in production presented the same error a couple of days later, again, restarted IIS and works for now.
I've checked the registry and the relevant tag exists with the right UUID and correct permissions.
It doesn't affect all sites on the server, only all sites in a particular application pool.
The application pools use a domain user identity and sites are split up into a number of shared pools.
I've now determined what was causing the above problem...
Our sites on IIS run in a number of shared application pools running as a domain user. We also have a Windows scheduler job which runs a number of scripts over night which also run as the same domain user.
It seems there are cases when this scheduler job runs it interferes with the IIS worker processes. When it completes and ends its user session it unloads the registry file in memory, which the w3wp.exe processes could also using.
This error is presented in the Event log...
Windows detected your registry file is still in use by other
applications or services. The file will be unloaded now. The
applications or services that hold your registry file may not function
properly afterwards. No user action is required.
Along with references to the w3wp.exe processes currently running.
It was replicated when I terminal serviced in as the domain user and logged out again after a period of time. The event log presented the error and the sites all bombed shortly afterwards.
Running the scheduled job as a different user has fixed this issue for us.
I remember having an include file for ADOVBS.inc with all the ADO constants inside and including it as a standard ASP include inside my global include file which is included on every page on the site.
This was before I used the META way of including the file.
So maybe a last resort is to revert to that method of loading in the ADO constants.
It seems like some sort of threshold is being hit, CPU/Memory?, which then prevents IIS caching/loading the file in from the registry. This then causes the error and a recycle of the pool. As no redirect is being done to the 500.100.asp error handler page which hides the error details from the user. It would suggest the error is in IIS and related to the server.
Thanks
I have two servers sitting behind a loadbalancer in my service tier. Both of them should be identical - IIS setup the same, AppFabric (to keep two services warmed up), app pools running under either a service account or the app pool identity. On one server, everything works. On the other server, three of my app pools (the two that AppFabric is warming up, under the service accounts, and one that's just a standard app pool with no changes made from default settings) stop running almost as soon as I start them up (sometimes on the first request).
I get five of the following error in the Application log each time I try to start one of the app pools:
There was an error during processing of the managed application service auto-start for configuration path: 'MACHINE/WEBROOT/APPHOST/Site/App'. The error message returned is: ''. The worker process will be marked unhealthy and be shutdown. The data field contains the error code.
The error code referenced is 80070005.
This is actually for the same Site/App regardless of the app pool being started (though it may change after recreating the app pools).
In the System log, I get the following warning five times before it errors (Application pool 'AppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.):
A process serving application pool 'AppPool' reported a failure during application preloading or service loading. The process id was '2396'. Please ensure that all application preload or service settings in the application pool are configured properly. The data field contains the error number.
The error code referenced is 80004005.
The AppPool here is the one being started.
I've tried recreating; I've tried uninstalling AppFabric (but we need it, so reinstalled and still no go). I'm out of ideas. Any suggestions?
EDIT: I tried copying the applicationHost.config over from the working server, but that didn't work either..
EDIT2: One of the app pools works when running under a real user account but doesn't when running under the ApplicationPoolIdentity....
(Also, we had an issue where the site was running under 2.0 and the apps were running under 4.0. That may have resolved the ones that are running as the service accounts.)
I was just wrestling with this same problem for a few hours and found a different culprit.
I had added a new configuration section to my Web.config in a recent commit. I also added this section to a separate ERB file used by Puppet to generate a custom Web.config at the point of deployment. In this template file, I added the new section but forgot to include its declaration in <configSections>.
Once I added the declaration to the template, our app's test VMs were able to start up again and this error went away.
While the app pools for the applications were 4.0, the app pool for the site itself was 2.0, causing some of the issues. We also had inetpub on a different drive, and we had to grant access to SERVER\Users.
I am facing a problem while starting the websphere message engine for one of the application deployed on websphere. This application is getting deployed automatically as a part of the installation of Websphere Lombardi 7.2 express edition. It's using websphere 7 internally to deploy it. When I try to start the message engine from the administrative console of websphere I am getting following error:
The messaging engine ProcessCenter01.twperfsvr-twperfsvr_bus cannot be started as there is no runtime initialized for it yet, retry the operation once it has initialized. For the runtime to successfully initialize the hosting server must be started, have its 'SIB service' already enabled, and dynamic configuration reload enabled. If this is a newly configured messaging engine and it is the first messaging engine to be hosted on this server, then it is most likely the 'SIB service' was not previously enabled and thus the server will need to be restarted. The messaging engine runtime might not be initializing because of an error while trying to start, examine the SystemOut.log of the hosting server to check for error messages indicating the problem.
After restarting the server, the same error shows. Can anyone help me to to find what gets loaded as a part of "initialization of runtime"? Are there any config files etc. that I need to check to solve this issue? I am suspecting some missing configuration causing error to load the runtime for this particular application.
I too faced this issue today had to delete all the files under the message store
check the directory-file path mentioned in
Application servers > server1 > Messaging engines > XXX.server1-primaryBus > File store
Just Enable the SIB Services For the particular Server.
Example:Server-->Application Server-->click on Server Name-->right hand side we can see SIB services-->Check box the Enable services.
This will solve your problem
Recently I have faced the same issue when I rebuilt the jvms in UAT envt. After searching on web I found that because of the old messages saved in the message store(flat files in my envt) the messaging engines was not getting initiated. After deleting the old messaging store and restarting the servers it got initialized.
I have struggled with this problem too.
In our situation the problem was that the file message store location was used that was already created for a different (or old) message-engine.
If you add a busmember to the service-bus and use a file store implementation, then you need to supply the path for the store and log folder. Make sure these locations don't exist yet, other wise you will run in the problem above. The message-engine for this member will use these folders.
If you have a script for creating the message-bus infrastructure, make sure that when you delete the bus or remove message-engines, that you remove the file store/log folders for these, before you re-run your script.
Another possibility is that you are using a external database as a data store, and the user that is used for the connection is not allowed to create a database. You might find a ffdc entry like this:
DB2 SQL Error: SQLCODE=-552, SQLSTATE=42502, SQLERRMC=DB2ADMIN;CREATE
SCHEMA, DRIVER=3.61.65
Then you have to go to your database administration tool and give DB2ADMIN the proper privileges. Then restart the server or cluster.
Finally this issue is been resolved. I did not create the schema in SQL Server with same name as that of the username I gave to connect SQL Server during the installation of WLE 7.2

I'm trying to deploy a winform application with IIS and ClickOnce. I can access the publish.htm page and the install even starts when I click on the provided link.
However I get this error during the installation process:
Downloading http://MyWebSiteUrl/.../Interop.SHDocVw.dll did not succceed.
The remote server returned an error: (500) Internal Server Error.
Can anybody help me out on this ?
Thanks,

I found out that I needed to check "use .deploy file extension" (under properties>Publish>Options>Deployment
[Answering this old question because it comes up as the best match in my case and the accepted answer was of no use to me].
Background, in an IIS hosted ClickOnce scenario, the downloadable components are itemized in a manifest file at the root of the deployment (that's how you can specify a single download link and deploy all the supporting components).
I was converting a tested application from a WiX installation to a lightweight version with ClickOnce and received the HTTP 500 error without anything else in the logs. Naturally, I failed to think it through and instead found myself getting dragged down the rabbit hole on the internets, with instructions for detailed logging, magic spells, etc.
Upon more sober reflection, the problem was simple and I should have been able to tell immediately from the IIS log: a 500 followed by a 0 is shorthand for 'you're an idiot, the content isn't where you said it was' and it had almost nothing to do with ClickOnce.
I had copy/paste/edited an existing download link template in MVC that was in use for simple apps and it happened to cater to only two levels of subfolders in the manifest. When I ported a more complex project structure, I ended up leaving items in a Resources sub-sub-subfolder that looked fine in the manifest but the path was being truncated in MVC so that the related item could not be found.
Moral of the story - if you get a 500 error always check first to make sure your non-functioning appliance is plugged into a working outlet...
