We have an XP SP3 machine where Office 2007 standard appears to have become corrupted. When we try to open word or anything it says the source file cannot be found. If we go to add/remove programs and try to click change to repair it, it just hangs or says the "langauge of the installation package is not supported by your system". If we do an uninstall it gets partway through and then says there was an error in the uninstall process and the log shows an msiapical failure. We have removed all of the Office 12 files and used the following article to try and remove it but it will still not remove fully or reinstall. http://support.microsoft.com/kb/928218
As a bandaid we have loaded an old disk of Office XP and it works except Outlook will not open as it is looking for the msocache source for Office 2007. Also some of the local documents were saved as 2007 format so they will not open with XP. It did let us start to install 2007 after that registry article was followed but it gets partway through and says it encountered an error. If we try to change or remove it from add/remove there are 2 instances of Office 2007 listed but it gives the language error when we try to remove it. ANy ideas?
