Application Installation Error

Hello

I am working on XP Embedded for several months. The most of difficult thing
what I feel is " application installation" and " finding proper Component "
..
Also I have to reduce OS size as I can do.
It so hard to make XPE OS to support my application.

I'd like to install "RSLinx" program which is communication program made by
Rockwell Automation.When I install this program in the XPE, error was
occurred.

"Error executing api , HResult = 0xH"

Which component is what I missed ?

Could anybody give me tips or advice about this ?

thanks
