I have a question, and perhaps a problem. I wasn't sure whether I had the 64-bit version of Calibre, and when I updated I downloaded the 32-bit version. It said it needed to make changes to Microsoft Office (!), so I cancelled the installation. It then prompted me whether I wanted to undo changes and I said no, but I believe I should have said yes, although I can't remember the exact wording of the prompt.
Do I need to undo the changes made in the cancelled installation? If so, how do I accomplish it?
Thanks in advance for any assistance.
