Hi, click on Start/Run. Go to the drivers/install folder under the program folder. (like C:\Program Files\ideCAD\ideCAD Static 7\Drivers\INSTALL) Type "C:\Program Files\ideCAD\ideCAD Static 7\Drivers\INSTALL\haspdinst.exe" -r -fr -kp -purge -v press enter. After the driver uninstallation is finished, turn the computer off and on, then; Type "C:\Program Files\ideCAD\ideCAD Static 7\Drivers\INSTALL\haspdinst.exe" -i -kp -v and hit enter. After the driver installation process is finished, try to run the program again.
