Kay,
The "Device driver software was not successfully installed" message would need to be looked into by Blackhawk. I haven't had issues with that but it has been a while since I have tried so it could be a compatibility issue with a newer Win7 service pack.
Since I have CCSv4/5/6 installed on all my machines I have newer OS drivers from those installs. That might actually be a solution. You could download CCSv6 and check the box to install the drivers for Blackhawk. That would get you the latest OS drivers for the emulator. CCSv6 can be downloaded here: processors.wiki.ti.com/index.php/Download_CCS
