Hello -

In your Project Settings under Platform >> Windows >> what is Targeted RHI? Chances are if your CPU needs OpenGL command your packed game will also need to be set to use only OpenGL and not DX.

Hi ,

We haven’t heard back from you yet, so I’m resolving this post for tracking purposes. If you’re still having a problem packaging your game with this error, please feel free to respond with information requested by Eric above, and we can continue investigating.

Hi, actually I’ve got error when compiling (for windows, but for html too).
Changing parameters Eric suggested didn’t resolve issue.
It seems also that this error blocks visualstudio project generation, and btw html run. Working on 4.10.

Hello Teapot Creation -

Can you try moving your project to a location with a shorter file path; it looks like secondary warnings listed in information provided by indicate that location of files are in a file path that is too long for windows and Engine to read correctly.

Thank You
