The new ZW 5 is available on this page below.

ZW 5 runs on 64-bit Windows with reasonably modern specifications. You need Administrator rights to install it and an internet connection for registering the installed software.

If you receive a message like this when installing ZW, you can safely click on the bottom left button, and go ahead with installing. This is just a warning, since Microsoft doesn't trust me yet. That's a matter of time. It's certainly not a virus warning or something like that. ZW-Scoring is clean and doesn't install anything else besides the ZW program and the files it need


If your installation fails with unclear messages, try to disable your virus scanner (and turn it back on right after the install). Some virus scanners (like Panda) are extremely strict, I really wonder what software they do let through. 🙂
Running the software after (re)installing is not a problem.

You can contact me through my Facebook page (see menu on the right) or mail me at zwscoring[at]zw-scoring[dot]nl. Replace the [at] by @ and [dot] by . before sending the mail.

ZW is free software, but if it is of value to your club you can help me cover my costs by donating. Thank you!

ZW-Scoring version

For ZW 4: In some instances it may be needed to activate the Windows Compatibility mode since ZW 4 was written for an older version of Windows than 7 or 10.
For an instruction on how to do this click on the link below. Choose the Windows XP (Service Pack 3) option as indicated in the example.
