My main part during the Beta testing period was to remove and to reinstall PSPX4 under 18 different scenarios on 6 different operating systems. Including all interruptions in between, I might have installed/reinstalled PSPX4 about 400 times.
While doing it, I never had any problems reinstalling PSPX4. (Compare to X3 which was a pain

)
There is indeed a tool for PSPX4 which is - please follow this advise - only for customers who can't remove the program from the Control Panel.
PSPX4 contains a new removing tool inside the program and removes all dysfunctional program parts already by using only the Control Panel.
[Update]SP1 has nothing changed. Please use Control Panel and in case of problems the tool.[/Update]
