When i execute the following in a script in Win7 - 64 bit:

EnvGet, BitVersion, PROCESSOR_ARCHITECTURE

the BitVersion variable has "x86" instead of "x64". Also, A_OsType has "WIN32_NT".

Is this a known issue?

EnvGet simply retrieves environment variables - obviously the environment in which AutoHotkey is running has a variable PROCESSOR_ARCHITECTURE with the value "x86". If you're wondering why it isn't "x64", that is because AutoHotkey is a 32-bit application and therefore runs under Wow64.
That is what it is supposed to be. "Win32" does not necessarily mean "Windows 32-bit". Wikipedia may shed some light on the topic. See also: A_OSType and 64-Bit Vista.

You can query the PROCESSOR_ARCHITEW6432 variable in a 32-bit app (such as AHK) to see if you're running on a 64-bit platform. If it exists (i.e. is non-blank), it should return AMD64 if you're running under an Intel (non-Itanium) or AMD 64-bit platform (and return IA64 for Itanium, though I can't personally verify the latter).
