Solved "Class is not registered" , error 0x80040154

I was also able to fix mine by converting my servicing stack TI worker location to hex UTF16LE and modifying the regedits you had in SFCfix. THANK YOU

You take the location of your most recent TiWorker : C:\Windows\WinSxS\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.26100.4651_none_a510910d775cffb2\TiWorker.exe

SFCFix.exe smoothly applied script SFCFixScript.txt that I had modified to contain hex addresses of my most recent 64bit and 32bit TiWorker.exe.

Stupid question. Did you reboot after running the fix script?

It could be a different registry that has an error. I cannot access your upload to one drive BTW. I think the SxS hive file is supposed to show the registries with invalid entries. I am by no means a pro at fixing this issue.

Yes, rebooted..

Hive file is just an export of
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Winners ,
no annotation.

You can try the way I formatted mine with the back slashes etc. I edited mine to include your hex.

Sorry I can't be much more help there is a component scanner from the same company and a forum post on how to get someone to look at your component registries.

What you are doing for me is to keep me both
- involved with the problem generally, and
- attentive to these particular registry values..
With gratitude I report a bit of progress, and what I did to get it.

Progress is that operation sfc /verifyonly completes.

Still the DISM failures.

I had been thinking that the SFCFix thing with hex encoding was an unnecessarily indirect way to modify registry data in this case. Today I took time.to look at these data in registry, saw that SFXFix applied data were truncated, manually inserted the text.

Next I have to examine CBS.log.
