[VB2008 - Word 2003 Add-in] Problems setting up installer

Hi

After hours i found a simple walkthrough on how to go about setting up my project installer for an addin i made for word 2003.

i have a problem though with prerequisites, im surposed to see Office PIA 2003 and VSTO 2005 SE in the list but there not there.

i double checked and i have them installed on my pc, is there any reason why they are not showing?, i downloaded the redistributable files again and reinstalled them and its still not showing,

im sure the installer will work on my pc but what about another end users pc, i really need to check for these files.

any ideas?

thanks
