Bit Che 3.5 Build 18 is running fine. I decided to update and downloaded 3.5 build 26 and it just will not install. The portable version doesn't run either. I tried uninstalling build 18 but did no good..... Build 26 will not run or install at all... I reinstalled build 18 and it was fine.
I'm running MS Vista Ultimate x86 SP2..
What could be the problem?
