OK thanks.
From what I could see, the MIT documentation does not explain how to apply a hotfix to an existing Enterprise Guide installation...e.g. there is no Software Depot and no Base SAS for Windows on the PC, just EG.
The prompt is:
"To install maintenance, please enter the location of your SASHOME directory. This is the directory where you first installed SAS, and should contain a filename called sassw.config."
No sassw.config file exists under C:\Program Files\SAS. I found some info on this file at:
http://support.sas.com/resources/thirdpartysupport/v92/AlternateJRE.html
Anyway, we will contact Tech Support.
