Hi Phil,

I can help you to fix this issue. Can you tell me the list of the files in the folder that is designed by the error?

And in the parent folder, there should be a zip file with the same name, can you check if Pharo.exe is here and if the file list is the same?

It will be nice if you can serialize the stack and send it to me / post it in a new github issue: https://github.com/pharo-project/pharo-launcher/issues .
