Hello, so I'm trying to get into Mining bitcoin but I can't download or work OpenCL.
If I try to open it, a black screen with a message pops up for literally a split second making it impossible for me to see what's wrong. Any help please?
You might be trying to run a miner directly.
Make a shortcut, then follow instructions for that miner to add "flags" to the shortcut, then launch from there.
You are seeing the CMD-line interface launch then quit because no flags are present telling the program what to do.
Alternatively if you are on windows (I suspect you are) Use GUIMiner which provides a visual interface that you can launch like a normal program.
