If Visual Studio 2010 Beta2 (all systems) or RC (Win7) crashes every time at startup, you may have hit a known issue that we are working to resolve. It is uncommon (but possible) to update fonts in a strange enough order to cause the font cache to think a file has gone missing. Once this happens an exception will be thrown causing Visual Studio to crash. We have fixed this for Vista and XP (RC & later builds) and will create a QFE for Win7 in time for the release of Visual Studio 2010. In the mean time, please work around this issue with the following steps.

1.      Stop Windows Presentation Foundation Font Cache 4.0.0.0 service (or kill WPFFontCache_v0400.exe proc)

2.      Delete *.dat from…

a.      XP -  %SystemDrive%\Documents and Settings\LocalService\Local Settings\Application Data.

b.      Vista/Win7 - %windir%\ServiceProfiles\LocalService\AppData\Local\.

3.      Reboot and you should be able to use Visual Studio.
