Hi,
I've got some output from msiexec.exe to help debug this. I can't seem to uninstall (2.2.0), or install (3.0.0) VirtualBox on a Windows7 laptop that had 2.2.0 previously installed. Below is the MSI log. It seems to fail in the finalization step where windows is attempting to uninstall drivers (install step UninstallDriverPackages fails). Any hints would be appreciated. On a positive note, 2.2.0 seems to be running OK on Windows7.
Thanks,
Tim
