apply to ZWCAD 2017


When uninstall ZWCAD and install the new version, sometimes we may encounter issues like

1, cannot continue to install ZWCAD on this machine.

2, "Install" button is gray

3, ZWCAD installation failed.


The cause is that after uninstalling ZWCAD, there are still some residual information in registry. 

First of all, it is recommended to run the attached tool to clean them, then try to reinstall ZWCAD again.


ZWCAD2017FixIt_XP32.exe is only for XP 32bit OS

ZWCAD2017FixIt.exe works for other OS including XP 64bit OS



If the tool does not work, please try to clean up registry manually.

1. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

(delete all options starting with "26A7C767")
