This software is built as a Win32 exectuable and will run on most Windows Platforms, 32 and 64 bit.  Windows 7 could be problematci if you havenot applied all of the mandator security updates and all the recommeded optional updates.  It will also run on a Mac and Linux under the WINE emulator with the WINEPFX set for Windows 8 or later.  FCCLookup users will find the loading and populating of the databases duirng the update process is much faster with this program.  However, the process seem to be slower when running the program in the WINE Emulator.
