Answer 1

I ran into this same error being thrown when I deployed my application onto a machine without a fully activated and licensed installation of Excel. I spent hours trying to diagnose the issue. Make sure you check your Office installations to make sure they are complete.

Answer 2

I ran into this issue with Word and my solution was uninstalling OpenOffice. I'm not sure if there's another solution but most likely has to do with the dlls and a conflict with the default file handler for the particular files you are generating programmatically.

This would explain why a restart helped another user.
