I got the command to work but got the following error:
LogWindows: Error: Fatal error: [File:D:\Build++UE4\Sync\Engine\Source\Runtime\PakFile\Public\IPlatformFilePak.h] [Line: 219]
LogWindows: Error: PakFile was frozen with version FPakInfo::PakFile_Version_FrozenIndex, which is no longer supported. Regenerate Paks.
This is a game pak file, and I know for a fact that others have been able to open it to mod without having to regenerate it; what do I need to change in order to fix the compatibility with UnrealPak aside from recompiling or regenerating the pak (since I can’t)?
