Miniforge uninstaller fails on Windows 11 #550

Solution to issue cannot be found in the documentation.

Issue

On my Windows 11 machine I tried installing Miniforge and make it work with Zsh in Git Bash. I got it working once using PYTHONIOENCODING set to utf8 inline, but after adding this variable to .zshenv, conda activate base never worked again. Due to this I decided to try reinstalling a different version.

When trying to uninstall Miniforge through Add or remove programs window, uninstaller fails and reports:

I tried running the uninstaller as Administrator from the file next. Now it reported only

This is the detailed output I got.

The installer did remove the install directory, but entry in Add or remove programs list remains.

Is there a fix for this or is there possible to fully remove Miniforge traces manually?

I found a solution in https://stackoverflow.com/questions/73458524/importerror-dll-load-failed-while-importing-ctypes-the-specified-module-coul?rq=2

In my case the files ffi.dll and ffi-7.dll were missing in MINICONDA3\Library\bin. I found them in some packages running:

dir /B /S "pkgs\*ffi*.dll"

I copied the two missing ones over. After that conda was running again. Hope this helps.

Encountered the same issue. Seems after 5 months this issue still remains open. Can anyone make some help?
