Hi,
Yes it is actually possible to change the installed licence key.
You just need to temporarily edit the shortcut which you use to start ZionWorx.
First, right-click on the shortcut icon and choose 'Properties' then view the 'Shortcut' tab.
Next edit the 'Target' box to include the word 'register' after the filename e.g.
"C:\Program Files\ZionWorx\ZionWorx.exe"
registerThen click OK and run ZionWorx from the shortcut and you'll be presented with an Enter Key dialog box where you can enter the new details. Finally, re-edit the shortcut to remove the word 'register' again and click OK.
Hope that works for you!
