Determine if Office PIAs Installed

The install I am working on requires that either Office XP, 2003, or 2007, along with the corresponding version of the Office PIA, be installed prior to running the installation.

I know how to detect if Office is installed, but does anyone know how to detect if the Office PIAs are present? I was thinking of checking for one of the Interop files, say Microsoft.Office.Interop.Word, in the GAC but I am not sure how to do that without shelling out to GACUTIL.

Any help would be greatly appreciated.

Rob Mensching posted the results of his research into the PIA installer in several installments...

[LIST=1]
  • Creative Commons Add-in's Office XP PIA - Detecting Office XP Parts
  • Creative Commons Add-in's Office XP PIA - Conditioning the Office XP PIAs - Part 1
  • Creative Commons Add-in for Microsoft Office: Behind the Office PIAs.


    You appear to be on the right track ... the gist of his suggestions appear to be a matter of using the System Search to locate the unique signature (registry entry, existence of file, etc.) of a PIA file.
