I am not sure what the problem is here. I been trying to work and troubleshoot it at the same time.
1. I tried running the exe as admin.
2. I tried going to windows and uninstall and install the exe again.
3. On another try I tried Uninstalling Corona and manually deleting all corona folders and installing them again.
4. Tried restarting.
Maybe it keeps skipping and doesn't repair the folder.
