One of my issues is that I run a lot of Solarwinds products - SAM, NPM, LEM, UDT, Patch Manager, VIM, NTA, and Dameware. It gets somewhat daunting to figure out what is compatible with what.
How about creating an installation package that checks compatibility and versions of all your SolarWinds products, advises you of the pre-requisites, and downloads/installs them for you.
