Trouble-shooting

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.

OpenGL

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.

Laptop users with integrated graphics should visit their manufacturer's website for an updated graphics driver. This may enable your laptop to run a newer version of OpenGL with faster hardware rendering.

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.
```
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.

MSVC++ Redistributables

Some plugins (e.g. Autodesk FBX) may require Microsoft runtime libraries not found on your computer. Also, if you receive the following error message:

The application has failed to start because its side by side configuration
is incorrect. Reinstalling the application may fix this problem.

You may need to install the MSVC++ 2008 SP1 runtime redistributables.
