When i attempt to launch the add/remove role wizard, i get this error:

When trying Get-WindowsFeatures I get:

It sounds like windows installer is having issues as well as i am not able to install some programs or remove some programs.. when attempting to remove or install i get this:

Here is my dism.log

I tried sfc /scannow, dism /restorehealth, chkdsk, updating windows, mofcomp, re-installing windows installer (msi.dll, msihnd.dll msiexec.exe), different admin account. used MSERT found nothing. tried safe mode, didn't work. made sure msiservice was running. I'm out of ideas.

    Sounds good, you can also try a repair install by running setup.exe from the root of the install media, but I wouldn't hold much hope for this working. Time may be better spent standing up a new one, patch fully, migrate roles over and move on.

    Sounds good, that's what I would have expected. Standing up a new one, patch fully, migrate roles over and move on is the better solution.
