I'm using Windows 7 64bit.

Running e.g. "gem help commands" results in the following error messages:

~~~

Seems zlib.so depends on zlib1.dll, but the zlib1.dll delivered using the installer is a 32bit instead of 64bit DLL causing the errors.

Replacing the zlib1.dll in the bin/ folder with a proper 64bit version makes the "gem help commands" succeed.
