Failed Upgrade from ESS 3 too 4

OS: Vista home premium 64-bit
I tried to upgrade from ESS 3 too 4 but recived a blue screen at the end.
After reboot I didnt think the program worked as it should so I tried to reinstall it again using only the installation file for version 4. Now parts of the program is installed but only anti spam works. When I try to change anything inside the program it just gives an error and sugest that I dont have admin rights to edit its settings.
This is the bad part.

For some reason, I now dont have admin rights to reinstall it, Or to erase the files manually, or to even go too some of the folders where its installed at.
Uninstall under*Controll panel -> Program and Funktions* wont list the ESS.
UAC was turned off befor/during installing and there is only 1 account (Admin rights).
I tried a program that people have been linked to befor. http://support.microsoft.com/kb/290301. Program wont run directly and when I press *Save as with location* its not there.

I have had acces too everything befor I installed version 4.

I pray that one of you knows what to do. Cause im clueless
