What would cause ANY .NET application to crash immediately... except a project I create and Debug inside Visual Studio?
My software recently got deployed to a customer who said that the application was crashing immediately after it started.
After some initial debugging, the customer provided me remote access to one of the computers which was unable to run the application.
I found that the crash wasn't specific to my application.
Any application which depended on the .NET framework crashed immediately.
Conveniently, Visual Studio 2008 was installed so I created a quick hello world application on it and clicked Debug.
The application worked fine.
But, then when I tried to execute the generated binaries in the /bin/Debug/HelloWorld.exe directory outside of visual studio it crashed.
List of things i've tried (UPDATED) :
I checked that "Everyone" has Read&Execute permissions for c:\Windows.
To test that the problem was with the .NET Framework (and not my application), I attempted to download Paint .NET on to the computers.
The setup frontend crashed in the same manner.
Performed a repair of the .NET framework as outlined in http://support.microsoft.com/kb/908077 (Boy was this fun and time consuming).
No luck. Installed .NET 3.5 SP1 (before it just had .NET 3.5) Note: my application targets 2.0 so I did this more as a long shot...
But i learned in the process that .NET 3.5 SP1 also updates the underlying frameworks.
Ran Aaron Stebner's .NET Setup Verification Tool .
This tool indicated that .NET was successfully installed.
(I forget if i checked all the versions but at least 2.0 worked).
Tested some mini hello world applications which were targeted for .NET 2.0 and .NET 3.5 and both crashed in the same way.
Tried launching .NET apps via windbg cmd line.
Doing this did allow me invoke my simple hello world applications.
So, simple .NET hello world works when invoked by windbg or by launching via debug in visual studio...
But doesn't if i try to execute it standalone.
I created a dump file using WinDbg.
It wasn't all that revealing to me.

Sounds like you got yourself a "fun" one there.
I've no clue, but here's my karma-whoring stab-in-the-dark suggestions anyway.
1) In addition to the regular user permissions assigned by Windows, there is also a separate set of security settings specifically for the .NET framework.
If you have the .NET SDK installed, look for the "Microsoft .NET Framework Configuration" tool in your Control Panel (may be under Administrative Tools).
See if any of the settings are different there from your dev machine.
2) I'm guessing your customer is under the thumb of an IT regime at his workplace.
See if you or your customer can get your hands on a fresh Windows install where the program works and then, working with his IT group, apply one of their requirements (security settings, antivirus programs, etc.) at a time until your program stops working.
A good old last working state bug-hunt.
Of course, this assumes cooperation from his IT dept, so I hope your program is important to an executive somewhere.

There is no silver bullet fix and I do not think it is a permission issue.
Here is what I would try
If it is a 64 bit machine try and switch to 32 bit mode I have seen this with 32 bit dlls trying to run in 64 bit.
Create a new website on the server and run aspnet_regiis on it.
Uninstall and reinstall the 2.0 and 3.5 frameworks.
Besure and run aspnet_regiis when complete

Couple of more suggestions to try:
Just to make sure it isn't the vshost.exe issue, I would try running MyProcess.exe under cdb/windbg and see the behavior.
The issue looks like an Read AV and if the app works properly under debugger, I would try to repair my .Net installation, in case there might be a possible corruption in the way OS handsover execution of a .Net assembly to mscorwks.dll.

We had a very similar issue in a large scale deployment in all cases running the repair on the framework fixed the issue I would give it a try.

Launch it using WinDbg.
Using Son of Strike you should be able to see exactly why it is crashing.
There may be a low level assembly load error.
I have run down similar problems using WinDbg in the past.

Make sure the user is not launching the application from a network share.
By default, .Net throws a security exception when attempting to launch an application from an untrusted source.
You can change this behaviour using the Microsoft .Net Framework Configuration utility in Administrative Tools.

I had a similar problem a few months ago (I do not remember the error code though).
After trying many things, the following solved the problem (as far as I can remember):
Removing all temporary files in the .net temporary folder (and also checking the permission of that folder)

Since it doesn't happen on every client machine, could it be RAM?
Can you reboot the bad machine and run the memory diagnostic tool?
Could DEP have been switched on for this machine at some point in the past?
You wouldn't get a .Net exception for this kind of security because your app simply doesn't get to run so there's little chance to throw an error.

Based on your windbg output it looks like someone has injected a DLL into the process at process-launch, and that the injection isn't designed for whatever version of mscorwks that has been loaded.
If this is a casual workstation (e.g.
Secretary) I would have it confiscated for MIS/IT to inspect for malware.
If it is a machine sitting in a server room I would look toward the customer to perform a relocation to another machine.
I don't suspect this would happen to any other customer, and in 8 years .NET development the only thing that can (expectedly) cause the behavior you're describing is an attempt to run a .NET Application on a system with an older version of the framework installed (e.g.
Lack of support, results in a standard debug/cancel dialog on most versions of Windows) and that is NOT what this problem is.
This is also not related to Processor Architecture, Framework Version nor SP level, it is not related to any commercial AV software, nor any commercial network-security software.
It's clearly not something in your code, and I don't see that it is something you can fix for your client.
I know of no tool nor series of steps you can use to resolve this issue short of having the customer re-image the target machine.
Before they do so, again, have it ghosted by MIS/IT for potential malware (specifically, malware that wouldn't be distributed through the general public.)

Good luck.

May be this link could help you to resolve your problem Fixing The Error “.NET Runtime version 2.0.50727.3053 – Fatal Execution Engine Error” [.NET] .
What operating system (Windows XP, Vista, etc.) does your customers pc has installed?
Have you tried to uninstall the .NET Framework (not repair) completely and then reinstalled it?
