Getting the same “Failed to open descriptor file” error. The build runs fine from the original directory it was built to, but the error comes up when I copy the package to a network and try to run it from there. Disabling the substance plug-in isn’t an option, as that would require major rework of the project. Any other workarounds for this issue? This error is a show stopper and we need to get the package out to the client. Thanks for any help!
