You can manually uninstall Q2ID on your Mac by doing the following:
- Make sure InDesign is not running
- Navigate to your Applications/Adobe InDesign folder/Plug-Ins/Filters/Markzware folder
- Inside the Markzware folder you will find the Q2ID Plug-In, move it to the trash
- Empty the Trash
Once the above steps have been completed, Q2ID has been Deactivated. When you restart InDesign, Q2ID should no longer be present. You can now install Q2ID to another computer.
