Hey there!

I have a project that was created in UE 4.16 and recently upgraded to 4.17.2. Before said upgrade, it was packaged just fine (for Windows 32bit), but now it just fails with and “unknown error”. Here’s what the Output Log says (the .txt log saved has even less info)

Some possibly relevant info:

  • This was created as a blueprint project and later on some C++ classes were added (though they are not currently in use, just some tests);

  • The “Compile” button runs without a hitch;

  • When opening the project, I receive 5 “Failed to load Parent for Function” messages;

  • I also receive 3 warnings (all displayed twice, so 6 warning messages) when opening the project:

    LogModuleManager: Warning: No filename provided for module ExampleDeviceProfileSelector
    LogModuleManager: Warning: ModuleManager: Unable to load module ‘ExampleDeviceProfileSelector’ because the file ‘D:/Program Files/UE_4.17/Engine/Binaries/Win64/’ was not found.
    LogLinker: Warning: Can’t find file ‘/Script/OnlineSubsystemUtils’

All that said… Any idea what may be the cause of my problem?

Also not able to package a 32 bit exe. I’ve heard that Visual Studio 2015 may be required to package a 32 bit exe, but haven’t been able to confirm.
