I had the same problem as the user in this thread with the missing DLL for the BIOS Config Server:
https://community.ti.com/forums/p/319/890.aspx#890
I tried repairing CCS from the installer, but after the installer copied a bunch of files, the missing DLL was still not located by CCS. Based on the advice in that post, I then installed DSP/BIOS 5.33, and I was able to use the DSP/BIOS tools in CCS for configuring a custom project. For reference, my BIOS_INSTALL_DIR environment variable is C:\CCStudio_v3.3\bios_5_33_03.
Now, when I try to build my project, I get the following error:
Build error: cannot run C:\CCStudio_v3.3\bios_5_31_02\xdctools\tconf.
Where can I tell CCS to use C:\CCStudio_v3.3\bios_5_33_03\xdctools\tconf instead of the old one?

A restart of my system seemed to resolve this issue. I can now buidl with the tconf for the proper DSP/BIOS.
