VirtualBox installation causes PCA dialog popup

[diggie]

It seems that each time that I upgrade VirtualBox, I get the Microsoft Program Compatibility Assistant window popuping up to ask me if the application installed successfully.

There are numerous reasons that this can happen: ​http://msdn.microsoft.com/en-us/library/bb756937.aspx

It seems that a likely cause, although I have not investigated thoroughly with regard to VirtualBox (but have experience with other installers), is that neither the downloaded executable or the VirtualBox main executable seem to contain an application manifest with a compatibility section containing the Windows 7 GUID:

Note that the PCA wizard can cache responses in the registry, so if you don't see them on a test system this could be why.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags

Hopefully not just a quirk on my system :)

Please reopen if still relevant with a recent VirtualBox release.
