I am running a CPAP program for sleep apnea that ran fine in VMBox. All of a sudden when I start it an error message flashes on the screen and quickly disappears even though I hit the Pause button. Does anyone know how I can keep the message on the screen? Running XP in Virtual Box on Windows 8.1 Host.

I found the solution. I ran event viewer from Run-eventvwr. The problem has to do with .NET Framework 3.2 SP1. Going into Control Panel to Repair it.

I still get the error message. This is what it is. Can anyone tell me how to fix it?

I suggest that you go to that link to get support from Microsoft for their product.

Tell me, if you had had this crash when running on a Dell PC, would you go to Dell for support? A virtual PC is just a PC, there are few special rules.
