Set ArchitecturesInstallIn64BitMode conditionally

I use ArchitecturesInstallIn64BitMode=x64 and it works fine on 64-bit Vista/Win7, but on XP x64 it causes problems (regserver fails), so I want to set it only if the OS is not XP x64.

Is that possible?

There's no way to conditionally set the ArchitecturesInstallIn64BitMode directive nor decide if you want to run the setup in 32-bit or 64-bit install mode from script in any way (even ArchitecturesAllowed cannot be conditionally set). What I'd suggest as a workaround for your problem is to use the RegisterServer function from code passing to its first parameter condition returning True when you'll be on 64-bit Vista above system. Using the code from the reference, it may looks like this (the following pseudocode should register the OCX extension as 64-bit only on 64-bit systems with Windows Vista above):

RegisterServer(IsWin64 and (GetWindowsVersion >= $06000000), 
  ExpandConstant('{sys}\hhctrl.ocx'), False);
