.msi file gone and not reparable

There’s no ChocolateyGUI.msi in C:\ProgramData\chocolatey\lib\ChocolateyGUI\tools anymore. Instead, a .ignore was appended to the end, the problem with this is that my .msi in C:\WINDOWS\Installer\ is missing and I don’t know how to repair it, when I run FixMissingMSI, I get this error:

@brian6932, thank you, I have already fixed my ChocolateyGUI using this method earlier in April, just forgot to describe the steps here.

@ALERTua Update: I was cleaning up my packages, so I decided to take a crack at it again, and I managed to fix it.

1. You’ll need a spare PC with Chocolatey installed
2. Install the exact version you’re having uninstallation difficulty with on the spare PC, in my case: choco install chocolateygui --version=0.17.3
3. Once the install is complete, grab the following folders, and copy them to the affected PC in the same paths: C:\Program Files (x86)\Chocolatey GUI and C:\ProgramData\chocolatey\lib\ChocolateyGUI
4. Make sure that if the affected PC has C:\ProgramData\chocolatey\lib-bad\ChocolateyGUI as a path, to delete the folder
5. Finally on the affected PC, run choco install chocolateygui --version=0.17.3 --force, and now you should be able to upgrade and uninstall again.
