Xamarin.ios designer System.AggregateException: One or more errors occurred - xamarin.ios

I am trying to open my Main.Storyboard in visual studio for mac, and i am getting 'System.AggregateException: One or more errors occurred'. Note that i happened after upgrading Visual Studio to 7.3, the latest up to now and X Code to 9.2, also the latest available to now.
I am getting the following error screen

As I commented above, I have been having exactly the same problem for a week or two.
Originally, Visual Studio was installed under a non-admin user account (using an administrator password where prompted).
I eventually did a complete uninstall using the script mentioned here, and then reinstalled from scratch using an administrator account. This seems to have fixed the problem.
It seems that something failed silently during the earlier installation. I was a bit suspicious because the Visual Studio app didn't have its own icon - it was using the standard MacOSX document icon. Having reinstalled, it has the correct purple icon.

Error Rendering Control (type initializer PX.Data.PXLicenseObserver threw an exception) on a ListView page in Designer mode

I am trying to overcome this error in Designer Mode of any ASPX page,
for example, CS203100 out-of-box:
I am not sure when the error began, and not sure if this could be related to any recent Windows Update. I am working with AcumaticaERP version 18.1.102.0048 under VS2015 on Windows 10 Enterprise. The error occurs under TargetFramework 4.5.2 and also after updating to 4.7.1. Any help please would be great, thanks!
We ran into the same issue with a colleague and it turns out that Visual Studio was not running with administrative privileges. It looks like PXLicenseObserver tries to create a log file on initialization and it fails when Visual Studio is not running in Administrator mode.

Visual Studio 2012 Express is suddenly "incompatible with this version of Windows"?

I'm running Visual Studio Express 2012 on Windows 7. I've been running it with no problems for several months now.
Last Friday, when I shut down my PC, a lot of Windows updates were installed. This morning, when I started up and opened a VS2012 solution, I got this error message:
This program has known compatibility issues
...
Visual Studio 2012 Express for Windows Desktop is incompatible with this version of Windows.
There's a button for Run Program, and when I click it, the solution opens normally. I haven't changed anything about my Windows configuration. This happens every time I open a solution. Did MS release a flawed patch in the batch of updates that got applied last Friday?
EDIT: I'm not sure why people are voting to close this question. The answer that's been linked to isn't related to my issue; that answer seems to pertain to trying to open a VS2012 project in VS2010. I'm trying to open a VS2012 project in VS2012. If you really think that the question needs to be closed, please let me know why in the comments, so that I can change it appropriately.
The .NET updates installed on Friday were:
KB2805226
KB2805221
KB2804582
UPDATE: I gave up, more or less, and clicked the "Don't show this window again" checkbox on the error window. Visual Studio seems to be running ok.
I received the same message on Visual Studio 2012 Premium (on PC where Windows 7 re-installed in last month) - the suggested fix was "Update for Microsoft Visual Studio 2012 (KB2781514)" which seems to have fixed it

Install Visual Studio 2012 Update 2 solved my problem. No previous update needed for this one. Here's the descriptions of the update.
(I'm using Windows 8, installed all important updates for Windows, then tried repair Visual Studio in Programs and Features, problem still here until installed Update 2.)
I've been running VS2012 for about 2 weeks now since I clicked the "Don't show this window again" button. I haven't encountered any problems. For now I'm going to consider this an adequate solution.
I've just installed VS2012 at home and came across the same problem. The 1st solution I found is that webdeploy doesn't work after Oct 2013 and I should install Web deploy V3.0.
Done that, no joy. I let Win7 search for compatibility solution on-line and it found an update patch (KB2781514) which did work.
This is the same solution as mentioned before by #John M.
Should've looked here first, just posting this again if someone comes across this again these days..
Thanks to all other users who helped with this thread.
I had a similar problem with VS2012 awhile ago it was along the lines of:
"this solution has no errors and could potentially be damaged"
*yet still opened fine.
as far as fixing it went I performed a clean install of VS2012 and the error has not bugged me since in saying that I am probably out of date at this time and may find if I updated I would have the same issue.
Food for thought.
Even i had the same problem on Windows 7 with Visual studio 2012.
Installed Update for Microsoft Visual Studio 2012 -KB2781514 and it fixed the issue.
Note: "Just clicking on Run program was also opening up the solution file without any issues in my case."

Visual Studio 2012 disassembly error dialog

This is a general error with Visual Studio 2012 that has come up recently. While debugging any C++ application and after hitting a break-point, clicking "Go To Disassembly" will produce the following error dialog:
Disassembly cannot be displayed for the source location. Uncaught
exception thrown by method called through Reflection.
I've tried reinstalling and repairing VS2012 with no effect. Even the simplest console application will show the same error, so it's not specific to a project and has to be a problem with the system configuration. At this point I'm just clueless what module Visual Studio is failing to load - google hasn't provided any solutions either.
The only possible link could be my recent removal of older .NET Framework redistributable packages (since I've got .NET 4.5 SDK and multi-target pack, I figured the older ones weren't necessary).
I really need the disassembly view working (it worked quite well before) and I was hoping someone has come across this problem.
Solved: After downloading Visual Studio 2012 Update 2, the problem solved itself. I guess it was a bug with the vanilla release.

there was an error attaching the debugger to the role instance

I am getting an Exception when I am trying debug my application on Emulator (Web Role).
you can see exception by clicking following link
Configuration which I am using Windows 7 pro, VS 2012 Pro, Azure SDK 1.8
Hope it might help others.
I Also had the similar problem and I restarted PC and **Run Visual Studio as Administrator**.
And let Visual Studio start the emulator with same privilege resolved the issue.
I was using Visual 2013 and Web API application under IIS Express.
Do you have IIS added? Most likely it's already installed but you've to enable it via Add Windows Compoenents on Control Panel...
I had this same issue all of a sudden, luckly I remember changing the ServiceDefinition.csdef file. I rolled this back to an earlier version and the debugger ran again correctly. The only thing I changed in the 'broken' version was instance size from small to medium.
Go to visual studio installer(search it from window's start)
and update the visual studio.
After updating, hit modify
button, after that on right side you will find a box named
debug (or something like that), select that box
Then hit install.
Restart your visual studio and debugger will start working.
In my case it worked perfectly.
