The Enhanced Virtual 3D option is located under the View pull down menu.
If the Virtual 3D window does not open importing the attached reg key should resolve the issue.
Save the attached file to your desktop.
To load the reg key you will first want to make sure the Alpine Software is not in use. Close IntelliVIEW.
Go to windows search utility and type in: regedit
Select the Registry Editor:
When the Registry editor opens select File\import and browse to the RegDefaultPath file.
You should receive a message that it was added successfully.
Now you can close the registry and relaunch the software. Enhanced Virtual 3D should now work.
