I just tried to install VB 2.2.0 over a existing VB 2.2.0beta2 on WinXPsp3 (used this beta, because it fixed hibernation issues associoted with VTx being enabled on WinXP/IntelCoreDuo/>2GB RAM - Hosts).
Setup wizard ends up in a rollback at setup wizard (ending 'prematurely' at install procedure).
No, it is even not possible to uninstall the beta2 via Windows Systemsmanager (asking for VirtualBox-2.2.0_BETA2-r45227-MultiArch?_x86.msi in C:\DOKUME~1\Max\LOKALE~1\Temp\\VirtualBox\.
The file doesn't exist any more. Trying to change/repair the Beta2 installation also ends up in a failure message ('prematurely').
Rebooting does not fix anything for me, I also tried to install the 2.2.0 with Custom Setup Options it doesn't seem to play a role whether "Networking" or "USB-Support" is chosen at Custom Setup in the Setup Wizard, like reporte i.e. be MrEasy? in the EndUserForum?. http://forums.virtualbox.org/viewtopic.php?f=1&t=16197&start=15#
Extracting the MSI from the Installer-EXE and executing it, like:
VirtualBox-2.2.0-45846-Win.exe -extract
msiecex /i VirtualB....x86.msi
ends up the same.
At least, the 2.2.0beta2 installation seems to work like before that installation attempt :\
Any ideas, hints or even solutions to this are appreciated.
