I just installed Office 365 this week. During that same time, I was cleaning up the applications on my computer and deleted a few things that I don't use. One of those applications was an accounting software that supported some Microsoft Office add-ins that I had forgotten about. When I subsequently tried to open Excel documents, Word documents, etc, I was unable to do so, as it continues to try to load the above add-ins. Since it can't do so, it shuts itself down, tries to load again, shuts down again, etc. I can never get it to open so that I can remove the add-ins in question. Any tips on how I can finally get in and delete these things?

I know it's not a problem with my version of Office, as I've also installed it on my Surface Pro 4 and iPhone and have had no problems at all.

Thanks for any help!

Have you checked whether the addins have an installer listed in the Windows Control Panel, under Programs > Programs & Features? If there is, try uninstalling it.

Simply deleting application files is a bad idea. Software generally needs to be uninstalled if it's no longer needed. Regardless, if you navigate to the application template folders, you may find the templates the deleted addins used. Deleting those templates may get you back on track.

For Word you could look in either of:
(just paste the above into Windows Explorer's Address Bar)
Template filenames end in .dot, .dotx or .dotm. Word's default template is named Normal.dotm

Thanks for the response, macropod!

I checked Programs & Features, but the add-ins in question aren't there.

I also went to the application template folders and deleted the one template that was there, but I am still unable to open up a Word doc.

Any other ideas worth trying?

You might try using System Restore to revert your system to its pre-Office 365 state, but I can't even be sure if that would work.
