If DriverPack will not open or respond, it may be blocked in the Windows registry. Open regedit , search for the key disallowrun , and delete any entries for mshta to restore functionality.
Because DriverPack is often flagged for adware or malware, many technicians recommend Snappy Driver Installer (SDI) as a cleaner, open-source offline alternative.
Avoid the "Install All" button. It’s safer to manually select only the drivers you are missing (marked with a yellow exclamation mark in Device Manager).
