ryar, in the meantime before you can start a new thread, I made an icon for your Primo link from my mod v3.3. You can use this code instead of your in chuck88.ui:
<script sc_run_primo> run sc_run_base_mortscript 100 run 'START_APPLICATION "Extension\CwGoPrimo.mscr" ""' </script>
Then change the name of the icon link (2 places) in chuck88_800_480.ui to the one attached herein. Don't forget to rename your CopyTool.mscr to CwGoPrimo.mscr under the Extension folder.
You can safely delete CopyTool.exe.
I didn't see this til now, thanks!
