"unable to delete existing zip folder"

I’m an early user, working on a first project. I created it on a mac, installed it and it works fine. I changed one image of its content before rebuilding it for friend using Windows. The Build was successful and I sent the corresponding exe file. The recipient could’nt open it however. The message they recieved was

Install name of file.exe unable to delete existing zip folder. Please Quit all running copies of the Installer application and try again.

Any ideas what I’m doing wrong.
Thanks

Most likely, the user probably launched the file twice, and it’s running in the background and they need to quit it before installing. This is fairly easy to do in windows, especially if the user gets impatient.

Ask the user to reboot (or log out/log back in) and try again – does that fix it?

Apparently that worked… Thanks so much
