I have the same problem the original poster has. On top of that, it chokes on the packs. The first one started to install, then hung. On the second try it installed (or said it did). But then I tried the next pack, and it hung again, so I gave up. So even though clicking through the "out of resources" box it seems you can continue with the Rapture Pro installation, the fact that the next stage hangs makes me think the installation really is not successful. I uninstalled and retried a couple times (and with reboots in-between just to give it a clean slate, so to speak) but with identical results - or non-results, I guess. Command Center thinks it was installed, so the only option now is re-install, but the results are the same. I am on Win 7 SP1 64-bit with a 3.40 GHz processor and 16 GB of RAM. Sonar Platinum with all the options installed fine, and when I updated to Dorchester it went fine. But not Rapture Pro. I put in a request to Tech Support a couple days ago but haven't heard anything yet.
