Script or MI that runs based on 64 or 32 bit
This little batch file scriptlet will allow you to run a command based on architecture:
set ProgFiles86Root=%ProgramFiles(x86)%
IF NOT "%ProgFiles86Root%"=="" (
vcredist_x64.exe /q /norestart
) ELSE (
vcredist_x86.exe /q /norestart
)
As you can see replacing the vcredist_x64.exe /q /norestart with another command specific to 64 bit will run if it finds a Program Files (x86). Else, it runs the next command that would be 32bit.
There may be a more elegant way of doing it, but here ya go anyway. Plop this in a batch file and set it as an MI and you are able to have only one MI for both architectures.

Interesting. I've used

IF EXIST "C:\Windows\SysWOW64" (
run something for x64
) ELSE (
run something for x86
)

Batch files are scripts run by cmd.exe. But which cmd.exe: the one in %SystemRoot%\system32, the one in %SystemRoot%\SysWOW64, or the one in %SystemRoot%\sysnative? It does matter! Windows tries very hard to hide the 64-bit environment when you run a 32-bit executable.
I was totally baffled by these differences until I attended this one day online class:

Need some convincing? I found these two blogs useful:

I highly recommend Darwin's insights. Sande
