UnrealPak.exe not working

I am trying to unpack a .pak file with UnrealPak, what is the correct syntax? I tried this exact formatting among others:

C:\WINDOWS\system32>“C:\Program Files\Epic Games\UE_4.26\Engine\Binaries\Win64\UnrealPak.exe” -Extract C:\file.pak C:\Destination

What am I doing wrong?

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)?

If the package is encrypted, it cannot be decompressed with this tool.
