Crash issues after installing VS2010 Beta 2 / .NET 4.0 Beta 2

November 17, 2009

This is a random post, but I figure it might help someone, since I couldn’t figure out what was going on for the longest time.

I installed Visual Studio 2010 / .NET 4.0 Beta 2 last night. When I restarted my laptop, I noticed that both the Microsoft Online Services Sign-In app and the Curse-Gaming Client crashed. When I tried to start them manually, the same thing happened.

There were no errors in the Event viewer and no log files, so there was no obvious reasoning. Repairing the .NET 4.0 and .NET 3.5 SP1 installations didn’t fix anything either. The only clue I had was from trying to debug the crash in Visual Studio when prompted by Windows. Even then, the error was still cryptic: The type initializer for 'MS.Win32.Penimc.UnsafeNativeMethods' threw an exception.

Several Google searches later, I found the following fix:

  1. Run Command Prompt as Administrator.
  2. cd \windows\\framework\v3.0\wpf
  3. regsvr32 PenIMC.dll
  4. cd \windows\\framework\v4.0.21006\wpf
  5. regsvr32 PenIMC.dll

Once that was done, I was able to run both applications without error.
