I finally figured it out. Turns out my checker had a parent folder with an apostrophe in it ('). So I just moved it to another folder and it worked.check that the program has correct permissions to replace its own files. the error displayed there is normal, just means that the tool had closed itself before the update script tried to look for it and wait for it to close. after this and after sleeping 3 seconds, it would start deleting the program files and moving in the new ones. i imagine its failing to do that
Thanks for making this tool, it's absolutely amazing.
