When I installed a superpack on an AIX machine, I got the error ksh: ./pu: 0403-006 Execute permission denied when trying to run the pu command.
Release : 20.1
Component : pu
In the package, the postinstall command specified is:
/usr/bin/chmod 700 /opt/nimsoft/bin/pu
So on your AIX system, check the paths for the chmod command and pu. and is the nimsoft installation path the same as well? -> /opt/nimsoft/bin
You may need to add a New section, e.g., pu_command_AIX and then ftp the pu binary over from the AIX machine and then with 'Files' Tab selected, rt-click and add the pu binary, (since its not java), into the package under that section, then also enter the appropriate post installation command with the absolute paths, for that section.
