Built a new PC and just got Boinc up and running on it. Tried to attach Milkyway@home but got the message in the log "App version needs OpenCL but GPU doesn't support it"
GPU is GTX 550 TI with the latest drivers (306.23), Windows 64bit.

I did some searching, and made sure Boinc installed correctly, and the drivers installed correctly. How can I get OpenCL to be detected?
