Here is a list of solutions for common software and hardware issues.

Mouse Wheel Configuration

To use the middle mouse button for zooming and auto-panning, configure the mouse wheel to Middle Button. This can be found in the Windows control panel under the Mouse settings. See here for details.

Multiple Monitors

When using multiple monitors and NVidia graphics cards, it is recommended that hardware acceleration is set to Compatibility performance mode. This can be found in the NVidia control panel under 3D Settings | Manage 3D Settings. Note that if any NVidia settings are changed, Unwrap 3D should be restarted.


Ultimate Unwrap 3D utilizes OpenGL for 3D rendering, so it is important your graphics card fully supports it. It is recommended the Unwrap 3D program runs at the default graphics settings. If you encounter any issues, please check to see if your desktop has any custom hardware profiles enabled. This can be found in the AMD or NVidia control panel under 3D Settings.

Windows 10/11
  • If you try to run the installer and receive the error message:
    Windows cannot access the specified device, path or file.  
    You may not have the appropriate permissions to access the item.
    Visit here to resolve the issue. Since this file was downloaded from the Internet, you may need to unblock it. Right-click on the installer file and then click Properties. In the General tab, click the Unblock button if available.

Windows Vista (32-bit only)
  • If updating, uninstall all previous versions and demos of Unwrap 3D.

  • Turn off Aero by selecting a basic desktop scheme such as Windows Vista Basic or Windows Classic. This fixes refresh issues related to Aero composition.

  • Right-click on the Unwrap 3D executable file and choose Properties. Under the Compatibility tab, select Run this program in compatibility mode for Windows XP (Service Pack 3). Details here.

Windows 7/XP (32-bit only)
  • Turn off DEP for the Unwrap 3D program. In Windows XP, you can find DEP in Start | Settings | Control Panel | System | Advanced | Performance | Settings | Data Execution Prevention. In Windows 7, see Control Panel | System and Security | System | Advanced system settings | Performance | Settings... | Data Execution Prevention (tab). Your computer must be restarted. Details here.

  • For ATI/AMD cards, turn off triple buffering in the Catalyst Control Center.
