We've got a pretty large installation base spread out geographically and are trying to determine how many workstations have older versions of the 7.1.00 User client. Our 'official' version is patch 005. We've found several workstations with patch 3, etc.
We have a product that can query the workstations, looking at registry keys, existance of files, file sizes, dates, etc. I would like to use this tool to see how many workstations have something other than patch 5. Is there a registry key, or more reliable way to determine what patch level of client is installed other than looking at the size, date of aruser.exe?
I appreciate any insight from the experts.
