Hi Lisa
There are no duplicates. Below is a listing of my c:\TI directory (I've now installed ccsv5 in c:\TI), and my c:\Program Files\Texas Instruments directory. The ccsv5.4 version does not like having more than one copy of xdc, bios, or ipc. Please file a bug for this. Our team will be using CCSv5.4 soon and this is a real deficiency.
I have not tried NOT using the auto-discover. Maybe that would be safer.
Also, why in the Window->Preferences->Code Composer Studio->RTSC->products can i not delete yellow items in the "Tool discovery path"?
