In reply to KJ.

I suspect that the issue has to do with one of the Microsoft C runtime components not being installed.

SAS has long supported Windows 7 now with later releases, so if you can, you should try a later version of SAS. But if you cannot, you may need to go back and install Microsoft Visual C 2005 runtime, and then either reinstall the Enhanced Editor component or reregister the component as per the instructions in the SAS note.
