So HRP6 first, and then straight to XenApp 5 FP3?

Please read the readme for HRP6 FIRST to catch the prereqs before installing HRP6. FP3 is just a bunch of individual installs. Pick and choose which ones you want/need.

Since XenApp 5.0 is basically PS 4.5, can I upgrade straight to "XenApp 5 Feature Pack 3" or do I have to install "XenApp 5 Feature Pack" first?
