The readme file has more specifics. It is located at: C:\Program Files (x86)\Bentley\PowerGEOPAK V8i (SELECTSeries 3)\PowerGEOPAK\readme_PowerGEOPAK.chm. If you search for readme under c:\Program Files (X86)\Bentley, it is similarly named and located for our other products. Open the chm file (standard Windows help file) and click Requirements on the left side, then Minimum Profile. JPG attached.
