I am using InstallShield Professional version 7.01.

I need to install separate files on 32-bit vs 64-bit machines.

How can I distinguish 32-bit vs 64-bit in InstallShield Professional version 7.01?

The 2 methods I tried did not work.

--1-------------------------------------------------------------------
if (SYSINFO.bIsWow64 = TRUE) then
copy the 32 bit version
else
copy the 64 bit version

Get error message - error C8045: 'bIsWow64' : member name not found


--2------------------------------------------------------------------
GetSystemInfo( ISTYPE, nvResult, svResult );
if (nvResult = 64) then
copy the 64 bit version
else
copy the 32 bit version

Result - nvResult returns 32 on a 64-bit machine.

Thanks

There's no 64 bit support in InstallShield Professional 7 (it's 7 years old!). If I recall correctly, GetSystemInfo( ISTYPE, ...) is to distinguish between 16 and 32 bit.
Mybe you can call some Windows API or read a registry entry to detect 64 bit. Or upgrade to a newer version of InstallShield.
