The new ZW 5 will be available on this page later this month.
Please be aware that ZW is a Windows only program.
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.
It is my intention to expand ZW to MacOS and Linux in the future.
