Bits

Quick question - is there an easy variable to tell what bits a current operating system is running (32 vs 64)?

The OS_ver variable returns NT.6.0.6002 for VistaSP2 - but it does so for both Vista32 and Vista64. By default, most programs are installed in Program Files for 32-bit and Program Files (x86) for 64-bit. I'd like my scripts to be able to work for both OSes, so ideally I'd like to have something like:

let>OS=BITS_VARIABLE
if>OS=32
let>location=Program Files
else
let>location=Program Files (x86)
endif

run>C:\%location%\program.exe

without needing to figure out what value OS should have every time.

Well, actually you shouldn't assume any format for the program files folder. What you should do is determine what it is:

See:

If you use this from Macro Scheduler the by default you should get whatever is the 32 bit program files folder. So you don't need to know if the system is 32 or 64 bit - that's a misnomer when what you REALLY want to know is "What is the path of the 32 bit program files folder". (for all you know someone has changed it to be c:\fred's programs).

Thanks - that's even better!

And looking over GetEnvVar, it looks like if I need to get the bits to do something else, I can use:

GetEnvVar>Processor_Architecture,bits
