No, I only have one version of Office installed. It's a fairly new PC and it doesn't have all that much software on it.

The 'installing new feature' window comes up as soon as I double-click on the word.exe/excel.exe icon (or a shortcut to an Office file). I am not calling on any feature that wasn't there the last time I opened up Office. Once a feature has been installed, it should stay there, no? It seems like Office is losing some feature or other between times I use it (or as I am using it). It would be helpful if I knew what feature it was installing each time.
