Issues with the EAP2 installer

I have VS 2010 Shell and the full VS 2013. The installer acts weird when certain selections are made:

1- Unselect VS 2010, Select VS 2013 and select both dotPeek & R#. Nothing gets installed. After a second I get the "Install Complete" screen.. which didn't make sense.
2- Unselect VS 2010, Select VS 2013 and select dotPeek only. It gets installed.
3- After finishing step 2, I decide to install R#. dotPeek is already installed from step 2. The installer installs dotPeek again! R# doesn't get installed.

I found out I had to select VS 2010 as well and was able to install both. BTW, I don't think it makes sense to install R# on a shell VS. Shouldn't the installer determine if it's a full VS or the shell version. I don't know why VS 2010 is on my system. I am assuming it's installed because of SSMS?

Anyway, if I hadn't chosen VS 2010 and I chose it because it was a crap shot, I wouldn't have been able to install R#. Installing R# in VS 2010 shell hopefully has no negative effects,
