I am using Archlinux 64bit and playing C&C Generals Zero:Hour. At first, I made a 32-bit chroot as introduced here(https://wiki.archlinux.org/index.php/Install_bundled_32-bit_system_in_Arch64) and installed wine inside it. Without even any configuration the game run perfectly (in fact, even more stable and never crash than in Windwos 7 but a bit slower). Then, I enabled multilib support and tried the 64bit version. The game won't start and err:CoGetClassObject class {***(sorry I can't give it at the moment)} not registered I wonder if it's the same with other programs. Is 32bit wine better supported? Someone says that probably 64-bit side is missing some 32-bit compatibility libraries. I installed all the dependence of wine. What lib may I be missing?
