Download SwissSys, version 9.55 for Windows
(swiss9setup.exe, 12.2 Meg)
You can download a free evaluation copy of SwissSys. The evaluation version does everything the registered version does, except that you will be limited to two rounds of pairing until you register.

When you purchase a registration, either as a first-time buyer or when upgrading from a previous version (see Ordering), you will receive a serial number that unlocks the evaluation version. The Demo runs in the full USCF + FIDE mode. If you purchase the FIDE-only version the unlocking key you receive will convert the file to FIDE-only mode. No need to re-install in either case.

Click on the link below. When prompted, select "Run" to install SwissSys. You may also elect to save the program and install directly from your computer later by double-clicking on the saved file.
