ZW 4 is still available at the bottom of this page

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 5 runs on 64-bit Windows with reasonably modern specifications. You need Administrator rights to install it and preferably an internet connection for registering the installed software. You can find some more notes on installing issues further down this page.

ZW-Scoring version

Installation notes
If you receive below messages when installing ZW, you can safely click on ‘more info’, and go ahead with installing. Getting Microsoft to remove this ‘protection’ is difficult and costly, especially for small developers like I am.
ZW-Scoring is clean and doesn’t install anything else besides the ZW program and the files it needs.

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.

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.
