Tech Comm and CS4 Master Suites

Has anyone else tried to install the Technical Communications suite on top of the CS4 Master suite? We tried it here in our training facilities but could not have both installed at the same time. During the install we kept running into shared assets errors when we installed the TC suite over the Master suite. The only solution was to uninstall the Master suite then install the TC suite but then the same errors popped up when we tried to install the Master suite. So is there a way to have the best of both worlds?
