Hi,
This just happened to me for the second time and I wonder if it is the Uninstaller that is causing the problem.

What happens is that a Sim2Pack file will give a message that the JIT debugger is started (which I don't have on my system??) And then when that fails and I cancel out, I can delete the Sim2Pack file and all other files in that folder, but am not allowed to delete the folder itself. It claims it doesn't exist. I can move things in and out of it, but delete, cut, rename etc. give a system message that it can't be found.

So there it sits on my harddrive until I accumulate enough of these to reformat the drive.

Any tips on how to delete an "undeletable" folder?

Thanks, K

For the JIT error, try reinstalling the dotnet framework, then reinstalling Clean Installer (remove old reg keys first). This has long been a known issue with the Clean Installer.

For the undeletable folders, try this:

You can kill the file/ folder, or else the process that is locking it.
