I am trying to fold with my AMD HD 6950 but I'm getting `Error initializing context: clGetDeviceIDs` and `BAD_WORK_UNIT` errors:
> Graphic card: Sapphir HD 6950
> Drivers: Legacy 16.2 (beta) (exact same error happens with 13.12 drivers I was using for cryptocurrency mining purpose)
> System: Windows 7 SP1 x86
This error message usually indicates a missing component from the video driver install, the OpenCL support. This often happens with drivers supplied by either MS or other sources other than AMD in the case of cards from them, or nVidia for their GPU's. Did you get your drivers from AMD?
It is also possible that you need a more recent driver version. Someone who has a 6950 or similar GPU may be able to comment on that. The last version released for that series of cards is 15.7.

One additional note, the current GPU folding core - 21, has been reported to work better on AMD GCN based GPU's. I don't know if that applies to the error you are seeing, but the performance on the older Terascale architecture your 6950 is based on will not be as good.

32 bits is no longer supported by FAH, you need a 64 bits OS.
Also, Crimson Edition 16.2.1 Beta drivers doesn't have a functioning OpenCL driver, you'll have to stick with 15.7.1 WHQL.
