wine users - Nov 2011 - C&C Generals Zero:Hour won't start on my 64 bit OS

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?

Wine is 32bits so it doesnt run 64bits apps. (It doesnt matter if your linux is
64b)

Well, I have that game, and I can give you a tip.

The game won't run unless it finds a few required registry keys, which have
your serial number,  and the folder where the game is installed.

If you simply try to run a pre-installed copy of the game, it won't start.

You must either install it properly, using the same wine prefix you are going to
play it with, or copy the registry keys (that's what I do).
