InstallUtilLib.dll: Unknown error in CorBindToRuntimeHost
If you're developing with Whidbey betas, and you happen to have setup projects, beware when you upgrade the project to newer versions. The .NET Framework launch condition doesn't get updated and points to the previous .NET version you were using (the one used to create the project, more properly), and causes the ugly error at setup time (no compile-time error is generated :S:S).
So make sure you specify the appropriate Version property for the launch condition. Repro steps and solution are described in the
MSDN product feedback bug. Feel free to vote for it!
