Windows 10: "Class not registered" error with Windows 10 & Office 365 Installation

I keep getting the "Class not registered" error with Windows 10 when trying to reinstall the office suite. I've tried Fix 1,2,3, and 5 from this link:


https://www.****/knowledge/fix-class-not-registered-error-on-windows-10-solved/#Fix%203.%20Start%20Internet%20Explorer%20ETW%20Collector%20Service


I was not able to locate Internet Explorer ETW Collector Service or iCloud.


I have a programmable keyboard and when I open the app for that, I also get the "Class not registered" error.

windows 10 microsoft 365, xls file won't open, error "class not registered"

Cortana & Office 365 Integration

We are trying to integrate Cortana with our Office 365 subscription, but it never works. Here are the steps we have done:

• Turned on Cortona in the Office 365 Admin portal
• We are using Windows 10 1703 – connected Office 365 service to Cortana

Did the same on windows 10 mobile with no luck, Cortana says its connected to Office 365, but sees no data and we are getting zero errors

We went rough office 365 support first and tried all fo their suggestions, they kicked us over to Windows support which is currently closed.

We are on v1703 with all updates in place, it does not work on Windows 10 desktop or mobile

any ideas? I can give you all steps 365 support had us run through if that will be helpful

Thank you

Doug

thanks BulldogXX.

This did not work, unfortunately.

Right clicked, clicked open with Windows app (MS Excel not an option).

Same error message, "class not registered".

I have Office 365, renewed a few months ago.
