Installing RMagick on Windows

Question

I've done research on this and I've been at it on my one computer for hours and hours.

I've installed RMagick on my Desktop computer about 3 weeks ago, and it was fairly complicated.

I don't remember the exact steps I took, and I'm really frustrated.

I've installed ImageMagick onto my machine in the directory C:\ImageMagick

I've installed the Development kit too for Ruby.

I've also put the rmagick-rmagick-v2-2-g564f157 into the proper gems folder in my C: It's in C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems

I'm getting the following errors:

I will type: gem install rmagick -- '--with-opt-dir="c:\ImageMagick"'

and get the following errors:

Temporarily enhancing PATH to include DevKit...
Building native extensions with: '--with-opt-dir="c:\ImageMagick"'
This could take a while...

Gem files will remain installed in C:/Ruby22-x64/lib/ruby/gems/2.2.0
/gems/rmagick-2.15.4 for inspection.

I'm so frustrated at this point. It worked on my Desktop computer, but won't work here. Any suggestions?
