I just purchased an HP All-in-one desktop with Windows 8 and installed Microsoft Office Home and Business 2010. It was working perfectly for about a week.
Now when I open Word to create a document, I get this message: "Word could not create the work file. Check the temp environment variable". When I clicked on Help to try and debug this problem, I got the message: "There is a problem with one or more installed help files. Please repair your Office installation and try again".
I tried uninstalling Microsoft Office, but couldn't.
