All Microsoft Office Professional Plus 2021 Apps Do Not Update

Question

Microsoft Office Professional Plus 2021 (2021 MSO (Version 2405 Build 16.0.17628.20006) 32-bit)

All Microsoft Office Professional Plus 2021 (2021 MSO (Version 2405 Build 16.0.17628.20006) 32-bit) Apps Do Not Update:

Observation Summary: I cannot delete Office nor modify nor repair, nor update Office.

I had a similar problem perhaps 15 years ago with Microsoft Visual Studio Professional. At that time, I had expensive maintenance service on Visual Studio. With this service I gave the MS Technician permission to remotely enter my system and he messed around for an hour with my files and Visual Studio. As a hell marry, he inspected pertinent Registry Entries and found a questionable registry file. He deleted and replaced the entries with his own computers Registry entry and all was well. This may be the same issue.

I must confess the use of Registry First Aid ( https://www.registry-first-aid.com/ ) and DiskMax (x64) ( https://www.koshyjohn.com/software/diskmax/ ). Are these possible root causes of messed up Registry????

Initial Problem Statement: Upon manual initiation of update request > Applications (Excel, Word, Access, etc.) > Update Options > Update Now >Update Error code: 30015-28 (2147942487).

Hi,

Login with Administrator account to download the Office support tool to help you uninstall Office from PC completely:

After uninstalling, please go to registry editor and check if the keys are clean, if not remove manually:

NOTE: Serious problems might occur if you modify the registry incorrectly. Before you modify it, please remember to back up the registry for restoration in case problems occur.

Open the Registry Editor (press Windows + R, type regedit), navigate to HKEY_CURRENT_USER\Software\Microsoft\Office and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office, and rename or delete Office-related registry entries.

Then delete temporary files from PC: Press Win+R, type %temp%, and delete all temporary files. Also, clean the C:\Windows\Temp folder.
