Using 64 bit wuauclt from 32 bit command prompt

64-bitscriptingwindows-server-2008

I have a script that for legacy reasons needs to run inside a 32 bit command shell. This script also includes references to certain core windows binaries – most notably wuauclt but others as well – which are not accessible by default within the 32 bit environment.

This script is being run in several locations including many windows 7 and server 2008 r2 boxes.

I'm aware of the possibility to copy files from the system32 to syswow64 in order to get around this. Is there any better method – something along the lines of adding an entry to the path variable – which will allow me to fall back to these 64 bit binaries from within a 32 bit script?

You should be able to reference the 64-bit wuauclt.exe as %SystemRoot%\sysnative\wuauclt.exe from your 32-bit cmd.exe process.
