First, I should explain that the data on the machine in question is primarily test data. Moreover, there are multiple copies of test data on the machine(s) in question.

I assume that when you are speaking about the \softrak\system directory, we're talking about the application (not data) directories. Is that correct?

You're right about the older version of SSI2XL.DDL. On the machines in question it's ver 1,11,19,171. Can I just copy a current version of SSI2XL.DLL over the older version? There are a number of SSIxxx.DLL files in the \softrak\system subdirectory. Is there anything to be checked or concerned about there?

Thanks!
