How to descern within Installscript if running in x86 or x64

[LrngToFly]

Hi all-

In an installscript script file, I want to run one section of code if I'm installing on x86 and I want to run a different section of code if I'm installing on a x64 computer. Is there some sort of a built-in variable that I can do an If statement on to determine this?

Thanks, AL

For MSI projects, you can use VersionNT64 as part of a condition. For InstallScript code, you can reference SYSINFO.bIsWow64.
