When I try to install a program (SafeGuard Private Crypto) I get this message: "Error 1606. Could not locate network location %USERPROFILE%\Siste\." I also get this message when I try to uninstall another program. A look at MS pages has not helped me. Anyone know about this error message? I use CCleaner. Can this be the problem? I used Norton Antivirus earlier. I have moved "My Documents" from C: to D: Should I get a registry fixer to solve the problem?
