This error can occur when installing the Gryphon QR code scanner driver.
This is how you can fix it.
1. First execute these two commands in Command Prompt.
- msiexec /unreg
- msiexec /regserver
2. Then restart explorer in Administrator mode:
- Open Task Manager
- Go to the details tab
- Find explorer.exe and kill it
- Still in Task Manager, click File > Run new task
- Type explorer.exe and tick the checkbox for Create this task with adminisrative privileges
- Click OK
3. Then try to run the installer again. It should work now!
