Edited 07/18/2012: See updated post, Windows Installer Batch Script Revisited

Recently, I needed to write a script that would install multiple independent components onto Windows XP and Windows 7 machines. The Windows 7 machines would be both 32-bit and 64-bit architectures. The install routine needed to: Determine which Windows version it was running on Elevate UAC (User Account Control) on the Windows 7 machines. Determine which processor architecture it was running on (32 bit or 64 bit) Run other install routines according to the above findings and report on their success Run itself and other routintes from a UNC share It turns out there is no simple way to elevate UAC in a batch file. You have to drop to VBScript. The whole routine is a pain to write in VBScript though, because VBScript is a terrible mess of a language.

After some searching, I stumbled across this post with a great script by Evan Greene that I used as a starting point: http://sites.google.com/site/eneerge/home/BatchGotAdmin

Thanks Evan!

I wrapped some additional code around it to determine OS version and processor architecture.

Check it out:

Hopefully this will help you out.
