Larry,
The current version of SatPC32 works on both 32 and 64 bit versions. It is running perfectly on my WIN8.1 64 bit machine. My suggestion is to download the latest version from Erich's site. Your registration number, which you should have received with your original purchase, is good for all future versions, so there is no need to buy it again.
73s,
Alan, WA4SCA
