Outlook 2010 error "There was a prob lem starting PhotoViewer.DLL"

Question

I have Outlook 2010 installed on this brand new Windows 7 desktop. When we get an email with an attachment and double-click it, we get an error: "There was a problem starting PhotoViewer.DLL" blah-blah. See attached:

Note that if I drag this attachment to the desktop and double-click it there it opens it just fine in the Windows default photo viewer.

Any idea how to fix this?

Answer 1

Open a command prompt (cmd.exe) with admin rights and run sfc /scannow to check Windows for damaged and missing Windows files.
