UE 4.8.1 Windows Shipping Packaging Issues

When I try packaging my game that runs on UE 4.8.1, it packages fine in shipping mode, but as soon as I try to run the executable, I get the following error from a message box:

Failed to open descriptor file ‘…/…/…/GameName-Win32-Shipping/GameName-Win32-Shipping.uproject’

Edit: Development builds work, but not shipping in either 32 or 64 bit mode.

Solved the issue. Disabled the Substance plugin which then allowed the executable to work, but was still throwing up the following errors about Paper2D:


Even though my project doesn’t use Paper2D in any way, I enabled the plugin and that fixed these warnings/errors.
