I'm pretty sure we can solve this, we have RP running in Parallels already so we know it's possible.
I've seen this behavior from RPA before when running in a virtual environment. I had installed on Win7 (today) in VirtualBox and it just couldn't connect when using NAT (shared) connection. It can connect when using a bridged connection but we'll need to make sure it's set right. We'll start with some basic stuff first.
1. Set Parallels to use Bridged mode and select the network adapter you have in the computer. I can't get a screenshot of Parallels networking configuration but this screenshot from VirtualBox should contain the same information. Perhaps Jeff (who we got it working on Parallels previously) might be able to help with the Parallels networking setup screens seeing as I can't see check them myself.
In this case, the network adapter in my PC is from Marvell. Yours will be different.
2. In Win7 make sure that the network type is set to home. If it's set to public your AV/Firewall (if you have one) or Windows Firewall (if you don't) could be blocking it.
3. Try again.
If it still doesn't work can you do this for me. In Win7 open a command prompt , type ipconfig /all and then post the results here for me.
If it works now, if your had to change your network type change it back and try RPA again. If it doesn't work again we'll have to set an exemption in your firewall.
Also, remind me do you only have a wireless connection?
