OK, trying to install ZLM 7.2 on SLES10SP1. Initially tried the 7.2 ir2 iso. Got errors on that. Researched and found "fix" of going back to 7.2 ir1.iso. Here's the problem, when I run the install from the ir1 iso, I get the exact same error as if I run it from the ir2.iso:

Installing Component 3 of 10: Data Store
Installing Data Store | | 0% Resolvable not found
Traceback (most recent call last):
File "/mnt/cdrom/data/zlminstall.py", line 561, in ?
File "/mnt/cdrom/data/zlminstall.py", line 434, in main
downloadID, transactID = zmd.transact(packages, None)
File "/mnt/cdrom/data/ZLMZMDLib.py", line 413, in transact
return(downloadID, transactID)
UnboundLocalError: local variable 'downloadID' referenced before assignment

Any ideas?
