CCS: RTSC New Platform Question. Only three device families show up, something is messed up.

Tool/software: Code Composer Studio

Hi,

I am trying to create a new RTSC platform from within CCS on Windows7. When I try to do this, only three device families show up and not C6000. See screenshot below.

I have four versions of CCS installed, all into their own folder.

CCSv5.5.0.00077

CCSv6.1.1.00022

CCSv6.1.3.00034

CCSv6.2.0.00050

When using CCSv5.5.0.00077, everything is fine and I get the whole gamut of device families. But the other three only show a couple items. What could be going wrong here and how can I recover. I even tried uninstalling CCSv6.1.3 and reinstalling but it didn't help. Since this issue is affecting multiple CCS installls, I'm guessing it's something more global, maybe something in my c:\ti folder. Could it b elated to this...
