Visual Studio 2012 Remote Debugging: Invalid access to memory location - visual-studio-2012

I followed the instructions in this link: http://msdn.microsoft.com/en-us/library/bt727f1t.aspx to install the remote debugger (2012) on my server where the application is running in hope to debug it remotely from my dev machine running visual studio 2012.
I cannot even get as far as viewing the list of processes to attach to on the remote machine. I keep getting "Unable to connect to the Microsoft Visual Studio Remote Debugging Monitor named [name]. Invalid access to memory location".
I have managed to successfully connect a few times but then the attach fails immediately then I cannot connect again.
This is causing huge issues for me as I cannot remote debug anything. I must be missing something glaring. Please someone give me a solution.

I've found the only way to correct this is by restarting Visual Studio.
Worked for me. I found it at this blog post about invalid access and remote debugging.

It turns out the one thing I missed was to tell Visual Studio where to find the .pdb symbols relating to the remote process. To do this go to Tools -> Options -> Debugging then in the Symbol (.pdb) locations add the remote location to the pdb files.
To clarify, I was attaching fine but could not break into code. Now I can. Be aware though that there are other hurdles before you get to my stage where I was attaching to the process successfully but could not catch a breakpoint.

I recently had someone else report this and debugged the issue on their machine. The "Invalid access to memory location" errors are due to an issue in Windows, it can be addressed with this hotfix.

I have had this problem in VS 2012, 2013, 2015 and 2017. Based on other answers it is likely that the problem is related to running a 32 bit version of Visual Studio on a 64 bit PC. Sometimes, as others have recommended, restarting Visual Studio fixes the problem but the best solution I've found so far is to start Visual Studio without a solution, open Debug -> Attach to Process, change the Connection Target to the remove server and wait for the process list to load. Then Cancel, do not attach yet. Load your desired solution and then come back to Attach to Process and the remote process list will still be loaded. Connect to your desired process and everything should work properly from then on.

Remote debugging a process that crashes on launch using Visual Studio 2012

I recently converted a mingw/cygwin build to a Visual C++ cl.exe build and upon initial testing found it crashes at launch. I then installed it in my developer environment to debug it, under which it runs just fine. My initial suspicion was that I was linking to a different DLL in that context, but examining both processes in both contexts with Process Explorer showed that they were using the same versions of the same DLLs.
Since I can't reproduce the issue with Visual C++ installed I installed the remote debugger on the client machine, but I can't manage to attach to the process quickly enough before it crashes. Is there a good way to go about doing this? This would be easy if I could launch the process under the debugger locally, but that doesn't look like a viable option here.
Any help would be greatly appreciated. Thanks for your time!
You should be letting the remote debugger start the debugee process on the remote machine.

VisualStudio 2012 crashes on opening web-based project - Windows 7 - Windows error message

Everything had beed working great, but suddenly something happened and every time I try to open any web-based project (either MVC or just 'Open Web Site', any others are just fine), Visual Studio 2012 crashes with Windows environment message:
MyProject - Microsoft Visual Studio (Administrator): devenv.exe - System error
Exception Processing Message 0xc0000005 Parameters 0x000007FEFD4A718C 0x000007FEFD4A718C 0x000007FEFD4A718C 0x000007FEFD4A718C
ОК
I did not notice exact moment when it stopped working. And obviously I have different extensions etc. But I believe, I did not install any big soft these days.
I've installed Windows 8 though, but separatly - on separate volume to try it. Theoretically, it might affect my situation, but I don't know how is that possible - at least I don't know any explanations.
I've tried to refresh Visual Studio 2012 installation, even removed and installed it again.
However, at the same time, I have Visual Studio 2010 previously installed, and it opens web-based projects without any problems.
Mentioned error message above is, as I understand, some generic error message - googling did not help on its recognizing, so don't know what to do - don't really want to reinstall Windows because of that.
Does anyone have any thoughts? Thanks!
I really don't know what was the cause of the problem, but after all other tries I've applied all pending updates of Windows Update service and everything works well after that.

Visual Studio deployment error

"The application could not be launched for debugging. Please make sure the device is unlocked."
I am getting this error when I try to launch the app on my device for debugging.
I have tried the following:
Relaunch Visual Studio,
Reinstall Visual Studio,
Restart my computer,
I have selected both debug and release in the configuration window.
The problem is that its not getting launched even in the emulator. The emulator opens and never loads the app but gives the same error message. And I have tried to just open a new application on VS and tried to run the default application. That also gives the same problem.
Everything was working fine after I opened a few more projects for reference, It suddenly started giving this error message.
Make sure a Windows project is not set as startup(assuming you have both windoes project and phone project in the same solution). For example If your target platfrom is a Windows phone project WP7, then you cannot have a windows project as startup. This is a known reason for the error you mentioned.
Also what is the operating system you are working with? I know the error you mentioned reprorted on some OS's including Windows server 2003 and 2008. Try running your project in winsdows 7.
I suddenly got exactly the same issue today. I was coding like always and then I got this problem.
// P.S.
// Today I updated Windows from 8 to 8.1
// Then I installed VS 2013 preview
// But continued working in VS 2012 (I need R#)
// After ~ 5 hours of work I got this issue
I tried everything, deleted emulators from Hyper-V, deleted all virtual commutators, restarted VS 2012, restarted laptop, deleted Bin and obj folders from project, rebuilded project.
But nothing helped.
Then I tried to open solution in VS 2013 preview, and it works!!
I hope I help you with this answer.
If somebody know how to fix it in VS 2012, please tell us
I have a similar problem but I’m able to debug my app once I click OK on the error prompt following the “Launching TaskHost.exe failed.” message in the status bar. I haven’t been able to solve it but I’ve found a workaround that might also work for you.
Start the “Simulation Dashboard” under “Tools” and instead of starting the debugger the usual way build your project if needed and then try to start the debugger by clicking “Locked” under “Lock Screen” on the dashboard.
This answer worked for me.
Under the following:
Solution(Right-click) > Properties > Configuration Properties > Configuration
Ensure that your main project is set to 'Deploy.'

"A remote operation is taking longer than expected" x64

First off, I think I've been to every website and forum there is that's discussing this issue and I've tried many different things. I'm at my wits end. This is the dumbest thing and I just want to start coding again!
I'm using Visual Studio Express 2012 for Windows Desktop. I have a x64 project I'm trying to run in Debug mode using the local windows debugger. The only external library I'm using is that of which is required to run DX11.
I attempt to run my program and it freezes. A window pops up saying "A remote operation is taking longer than expected."
I click Terminate and another window pops up asking if I'd like to terminate the remote session. Why yes, I would.
Then it says, "Unable to start program (my path leading to my .exe). The network connection to the Visual Studio Remote Debugger has been closed."
To my understanding, because Visual Studio itself is a 32 bit application, it needs to use the Remote Debugger to compile to x64. Is that correct?
Regardless, I'm still failing to see where that would break down. I've ran several repairs on VS and upgraded to Service Pack 2 (or 1, whichever is the latest).
I've ran a windows repair and uninstalled any VMWare type stuff on my computer. I'm not using a VPN.
I've even copied msvsmon.exe from my laptop (working instance of the project) over to this computer and still no luck.
I'm about ready to Nuke my OS and do a clean install on everything. sigh
Found the problem. It wasn't Windows Firewall like other threads describe. It was my internet filter. I guess it decided to try and block msvsmon.exe because it was using the network. Adding it, along with WDExpress.exe to the application exceptions list did the trick.

How to get rid of the VMware error when starting Visual Studio 2012, but without disabling VMDebugger add-in?

I am getting the following error when starting Visual Studio 2012 as unprivileged user:
An error has occurred while trying to access the log file. Logging may not function properly.
A casual web search showed that the issue used to exist with VMware 6 beta, back in 2006. I also found one other user who experiences the same in a more recent VS version (2008) and it started only recently.
The title of the message box indicates that this comes from VMware. I have VMware 9 Workstation installed. The problem could be related to system updates or the update 2012.2 CTP and hasn't gone with the final 2012.2 update package.
The question:
How can I get rid of the error without actually disabling the VMDebugger add-in?
Temporary workaround:
There is a workaround, disabling VMDebugger in the "Add-in Manager". However, it even seems that unprivileged users are unable to successfully disable it. I had to start VS as admin (I am using SuRun for the purpose) to disable it and the error not reappearing upon next start of the IDE.
I had the exact same problem, this is how I solved it.
I monitored devenv.exe using procmon to find the log path, on my computer it was: %TEMP%\vmware-username
I checked the permissions on the log directory, and discovered that my user had no access - neither read nor write! I gave myself full access and deleted the old log files. That solved it for me.
I think this happened because UAC was disabled when I installed VS and VMware.
In Visual Studio, go to the menubar to VMWARE / About VMWare Virtual Debugger; the Debugger log file will be listed there, e.g. C:\Users\Phil\AppData\Local\Temp\vmware-Phil\vmware-vsid-1.log
Give your user full access to that file.
(This solution was for Visual Studio 2013, VMware Workstation 11.1.2, Windows 8.1.)
The fastest and easiest way to solve is...
1. Locate the folder %temp%\vmware-{username}
2. Delete this folder. The folder will be created by opening the Visual Studio.
Note: You need to open the Visual Studio without admin rights to resolve the issue!
Background: Mostly this happens if you use the VMware debugger plugin the first time under admin rights (because your app may need this right to run properly). This creates the folder under admin rights with the admin permissions. Everytime you open the Visual Studio with admin rights, you have no problems.
Examples
Windows: C:\Documents and Settings\<username>\Local Settings\Temp\vmware-<username>-<PID>.log
Linux: /tmp/vmware-<username>/ui-<PID>.log
