MK,
PROC SETINIT will tell you what you have licensed, not what you have installed. So if it says you have SAS/Access for PC files, talk to your local support folk about getting the additional pieces installed.
Another workaround might be to use Enterprise Guide to read the Excel files. EGuide is part of Base SAS for 9.3 and includes some of it's own routines for reading Excel (right now, I feel like EGuide has more features for reading 'difficult' Excel files than IMPORT does).
