Your assumption is correct.

I will do that, but isn't the error message different for that? Also it is a requirement for the install, and before the .NET 2.0 framework has always been installed before my install if needed. But it is worth checking out along with the Crystal framework.

I will check.

Yes customer emailed me the error and it is the generic "[your app] has encountered a problem and needs to close. We are sorry for the inconvenience."

I create a mutex, then I check for screen bounds then I display my splash screen. The error must happend before the splash screen because the user does not see the splash screen.
