Flatpak: cabextract can't find libmspack when installing d3dx9 or dxvk

[SuddenPineapple]

Describe the bug

Trying to install any D3dx9 related stuff in winetricks will cause an error where cabextract cant find libsmpack. It might be #2625 again. It is installed through Flatpak. I was using Ge-Proton but it still happened when I tried the normal 8.0 version of proton. I am trying to run the GOG version of Batman Arkham Asylum.This is like my third time righting a bug report so sorry if its messy.

Have you tried with Wine-GE-Proton instead? installing that with winetricks shouldn't fail

I'm not OP, but was having trouble installing d3dcompiler_43 and more following these instructions and getting the same error as OP. Using "Wine Manager" to install Wine-GE-Proton did resolve this problem. Thank you @arielj!
