Bug #: 28959
           Summary: C&C Generals Zero:Hour won't start on a 64 bit OS
           Product: Wine
           Version: 1.3.31
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

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. But is 32-bit wine more capable
than 64-bit even inside a chroot? Do you suggest using a 32bit chroot and wine
inside it rather than install it into 64bit directly?
