However "winecfg" does not allow me to input free form strings (at least I try and could not find a way). It does only allow me to navigate throught the file system and choose the application. And the "Libraries" tab, in winecfg, it is only for DLL's - I guess! (Am I wrong?)
No, it can be used for .exes too, you only have to specify the full name(e.g. "user.exe" for user.exe compared to "oleaut" for oleaut.dll)
I often use it for dplaysvr.exe, so it works
