Running on Windows 10, under Safe Mode, Run as Administrator. Log says every file permission fixes are done, no errors is present in the log.
While running, console windows are flashing over, displaying some errors. As no logging provided, I tried to catch them by the Pause key. Screenshot is attached.
Also, I've tested the program by deleting the permissions, leaving Administrators privileges only. The program should add privileges according to files\permissions\*.7z files, but the privileges were left unchanged after the program run.
