Q：Sometimes uninstalled ZWCAD and reinstall it, and the System alarm that ZWCAD has existed in your computer?

A: This is because the information of ZWCAD in regedit cannot be unstalled completely when ZWCAD was uninstalled. In this case, please delete the informaiton of ZWCAD regedit from the regedit path, such as “HKEY_CURRENT_USER\Software\Chinaweal Longteng\ZWCAD 2010 Eng”, after that please try to install ZWCAD again, it should be successful.
