I cannot install thin gem on windows. Something happen during build of native extensions.

Do anybody face same issues?

First, install the DevKit from the RubyInstaller for Windows website (which it appears you have already done).

Then install eventmachine separately from the git repository as Roger shows.

You should then be able to install thin from the gem.
