I have a Laptop Dell XSP M140 running on XP. For few month have problems intalling programs. What I did was to install them in a folder diferent than PROGRAMS, I created a folder called OTHER PROGRAMS. This worked for some programs but eventually did not work at all. So I started installing programs in SAFE MODE. I thought the problems were related to the NET framework since I got recently couple of errors regarding this. I uninstall the NET framework 1.1, kepth NET Framework 2.0 SP1. Tried to install NET Framework 1.1 again without success. I have not been able to install FRAMEWORK 3.5 update for weeks either, but I learned that some dll were missing from Windows32 (e.g. scrun, jscript.dll, vbscript, dixpex.dll ampmg others). I ran -Windows Script 56- couldn't install them [INF Install failure, Reason:Access is denied]. I ran NETFXSETUPVERIFIER and found

Downloaded from dll-com, could not install them. Then I tried to install -Windows Installer Cleanup Utility-, but failed to install it [Cant find script engine VBSscript] .......What might be happening? I think I got attacked with malware, I ran Malwarebytes and got this:[/size][/size]

Windows installer does not appear under msc "Services", but is on Group Policy/Computer configuration/Administartive templates/Windows Components. I Enable to disable it in order to install Windows Installer. I did not try to uninstall Windows Installer.

WHAT SHOULD I DO?
Thanks a lot, Ciro
