PlayOnLinux has never worked, so don't bother with that. It's malware.
By "portable preinstalled games" do you mean you copied the installation from elsewhere, or something like a repack?
Copying games like that rarely works, since you may not have the required system files installed that go along with them. You might go into Winecfg (in your terminal, just type winecfg and press enter) and in the libraries tab add the d3dx9 libraries. May as well add d3dx10, d3dcompiler, d3drm, dinput, dxgi, devenum, dbghelp, d3dxof (all libraries listed, there are several with different numbers). But my guess is that you'll need a reinstall, to get the required system files that came with the games.
