Hi All,
I have a fresh install of win10 20h2 with 365 office.
Msft word and excel won't appear as defaults.
Excel appears for .xls, but not .xlsx. and a couple of other extensions.
msft default apps in control panel won't list outlook as a possible default for email, and when I try to route .xlsx directly to the excel.exe in program files, I get the same error, 'This file does not have an app associated with it for performing this action..'
I've tried right clicking in explorer and opening with excel directly, and with file path, as well.

Running latest updates on 20h2 build 19042.630
and latest office v2011 build 13426.20294 click to run.

I've uninstalled office, with the cleaner, and reinstalled. i've tried quick repair, and online repair.
I can open any excel file from inside of excel.
I'm pulling my hair out with this one. Any help would be much appreciated!

Thank you in advance!!
