Can't run 2 copies of ArchiCAD7 on Mac OS10.3.6

[Anonymous]

I can't run 2 copies of ArchiCAD 7 in macOS 10.3.6

I have made a copy of entire folder and renamed the 2nd copy of ArchiCAD and still no success.

I am able to run 2 copies of ArchiCAD in Mac OS9.

I understand you need only copy the actual application to run 2 copies of ArchiCAD8.

Any suggestions or workarounds?
