WS 3.2 for Mac has permissions problems for other users

edit

WS 3.2 has permissions problems for other users. 'Permissions denied' error on open. Won't open pcaps 'permissions denied' although all 3 users are admin.

1. 2015 MBP 10.14.6 all updates
2. have not had this with previous WS versions
3. haven't been thinking about the chmod and path scripts in a while - but
4. WS is in $PATH for all, get info for WS app shows all users have permission, in theory
5. re-install / reboot / zap PRAM == same result

error text includes:
