[ruby-core:63148] [ruby-trunk - Bug #9936] wrong zlib1.dll installed on windows

From: phasis@...

List: ruby-core #63148
Issue #9936 has been updated by Heesob Park.


I confirmed the error message "%1 is not a valid Win32 application." occurred with 32-bit zlib1.dll and 64-bit ruby.exe combination.

I guess that Claudio installed Ruby 2.0.0-p481 (x64) to C:/Tools/ruby200 folder first.
And intentionally or accidentally, he installed Ruby 2.0.0-p481 to the same C:/Tools/ruby200 folder.
Or vice versa.

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.
