One of our client's PCs running Win 7.
MS Office 2010.
Dell PC, all Installed in 2011.
Word & Excel won't start.
"There was a problem sending the command to the program"
"Microsoft Word has stopped Working"
Tried all suggestions in http://support.microsoft.com/kb/921541
Cannot "uninstall" or "change" program from control panel
Really weird error "The language of this installation package is not supported by your system"
No malware. In all other respects system is fine.
