Some clarification is likely needed for this.
SAS 9.3 is supported on Windows 8 if it is the Education Analytical Suite. Also the SAS revision itself has to be a certain revision or higher as well. Please observe this sasnote: http://support.sas.com/kb/46/876.html
Note in the 9.3 section the fully supported revisions is SAS 9.3 TS1M2 Revision 13w18.

Using it will show you that SAS 9.3 is supported on Windows 8 and notice the comment section about the Education Analytical Suite.
I hope this help. Please contact SAS Technical Support if further assistance is needed.
