I am trying to add a button to a custom ribbon that will run a script file when selected. the script file is called "MORGAN_OLD-TO-NEW_LAYER_TRANSFER.SCR" and I just can't seem to get the syntax for the macro command entry in the CUI entry for this button. I've tried different permutations fo the following: ^C^C_SCRIPT c:\MORGAN\MCCO_AUTOCAD_2019\MACROS\MCCO-PT LAYER TRANSFER PACKAGE\MORGAN_OLD-TO-NEW_LAYER_TRANSFER.SCR with little to no success. I have 2 questions:
1. is it even possible to launce a script from a ribbon button
2. what would be the syntax to run this command without user interaction (except pushing the button)?
I was going to try and record a macro of the manual commands and launce this from the button but unfortunately our corporate IT has locked out the action recorder.
