Some of my friends have recently installed the program of ZWCAD 2009. But later they told me that they did not enjoy the 30-day evaluation period or even could not start ZWCAD. I asked whether they were using a Windows Vista system. They said “Yes”. In this case it is not a real problem of ZWCAD. With just some steps, you can make everything work.
First of all, please ensure that the Vista system is up to date. And it is very important to login Windows as an administrator before installing ZWCAD, as other non-administrative accounts are not fully authorized to make necessary settings to Windows for ZWCAD. Of course, the available disk space should be adequate as specified.
After the installation is completed, right-click the shortcut icon of ZWCAD 2009 on the desktop and select “Run as administrator” to start ZWCAD 2009. Next time you start ZWCAD, you just need to double-click the shortcut directly.
Perhaps you can also try another way. Right-click the shortcut icon of ZWCAD 2009 on the desktop and select Properties, choose the Compatibility tab in the ZWCAD 2009 Professional (or Standard) Properties dialog box, go to the Privilege Level section and check the check box of “Run this program as an administrator”, and then click OK to confirm the setting. To start the program, you can simply double-click the ZWCAD 2009 shortcut icon on the desktop.
With the settings above, ZWCAD can run normally with a 30-day full-functional trial period (if ZWCAD is installed for the first time). However, there might be some special cases, to which the solution above does not apply. For example, some special security applications might block ZWCAD. In this case, please check the setting of the security application or contact its provider for possible solutions.
