Operating System: Windows 7 Home Premium I recently got this Samsung R440 laptop and I've been having trouble installing downloaded programs, (ex. AOL IM, iTunes). Itunes won't even appear when I run the installer. AOL will say "NSIS Error: Error Launching Installer". I've tried numerous things: run as admin, cmd.exe (force install), and changed .exe into .msi. I'm wondering if this may be a problem with the registry, however I've even used Registry Cleaner with no luck. Does anyone have a solution? Do you need to look at my cmd.exe (/ stat)? hijack this? anything else? Thanks.
