Sometimes we will get feedback from our customer that ZWCAD cannot be activated due to the license manager freezes when click "ACTIVATE" button, or we fails to activate it on some computers, and we know that the license code has no problem (can be activated on other computers), you can send this tool to the customer to try troubleshoot.
This tool is from ZWCAD 2012 version, and it can activate any version of stand-alone license. If you find any problem, please feedback us.
