I just installed 0.7 on Windows 10. Adding DataFrames failed due to CodecZlib. I’m in a corporate environment and I don’t have admin privilege. Is that why?

I had the same problem on Win 10. Following the advice in the error message: `Pkg.build("CodecZlib")` with subsequent restart of Julia seems to have solved the problem.

I think this is a known issue ([https://github.com/bicycle1885/CodecZlib.jl/issues/24](https://github.com/bicycle1885/CodecZlib.jl/issues/24)) and is already fixed by [https://github.com/bicycle1885/CodecZlib.jl/pull/30](https://github.com/bicycle1885/CodecZlib.jl/pull/30). A new release has been tagged and now we are waiting for merge.
