Error Code 0x426-0x0

Question

I am suddenly unable to open Word or Excel on my PC, although I can continuer to use One Drive, message quotes error code 0x426-0x0. I have tried "Repair" in settings but that has not solved the problem. Neither has clicking on Reset. I am uncertain as to how best to proceed. If I read the instructions correctly, my next step is to uninstall Microsoft 365 (Office). I just want to verify that once reinstalled, will my individual files still be accessible in the new apps?

I understand that you are getting Microsoft Office error code 0x426-0x0 when you try to open Word, Excel. this is due to corrupted Office installations, disabled services, and antivirus software conflicts.

You can try the following:

1. First, press win+R to open Run Accessories. windowsR
2. Type the following command and click ok .

    appwiz.cpl
   

3. Select your Microsoft Office Suite software. Then, click the Change button to open the MS Office repair utility.

Your step #3 above doesn't make sense.

I do not see Microsoft Office Suite. The pictures below step #2 and step #3 are identical.

I installed Microsoft Office Suite several years ago from a "one-time use" code.

If I remove the software, I am unable to resinstall.
