Windows 10: Msiexec.exe Access Denied

Recently, I haven't been able to download certain things, such as UE5, because it suddenly stops downloading. I know it's because of Msiexec.exe, and when I try to force close it with task manager, I get an "Access Denied" error. I'm not sure what to do to gain access or even just delete the thing!!

All the regisry entries in your regfile are the same as at my virtual machine.

You can check file properties:







Or you can try to extract and copy this file (1903 x64) to your system32 folder:
msiexec.zip

Check your Event Viewer for warnings and errors at the time of an install attempt.

Otherwise, I am out of idea.

I agree with Ed although not sure in-place upgrade can help. But it is simple to try it. In the case of msiexec problem persists:

- install clean system
- install some imaging software
- make system image
- install all your software one-by-one using the following steps
-- install one program
-- test if msixec can run
-- if yes then make system image and continue with next program installation
-- if no then you discovered the problematic program; restore the system from recent non-affected image.

Good luck.

That's about what I had planned if I went down the rebuild route. Just with a few more steps. Well I haven't got anything better to do!

Clean install

backup (Image)

test msiexec

Update

Test again

etc.

Anyway, I'll install over the top. Just see if it works or not. Then we'll know for next time.

Oh happy days!
