Here is a proper solution for anyone interested, that doesn't mess up your current installation of mysql server. Download a zip file with mysql server 5.1 NOT the msi one. Make sure it's 32-bit NOT 64-bit. Since there is no installer file with this, create a folder c:mysql-gem-install - you can remove it once you finish. Extract all the files from the zip file into the folder you just created.now run this commandgem install mysql2 - '-with-mysql-lib='c:mysql-gem-installlibopt' -with-mysql-include='c:mysql-gem-installinclude'I just installed mysql2 gem v.

What solved my problem was:. Downloaded the lastest MySQL for windows 7 32 bits. Installed the gem with the following command: gem install mysql2 -platform=ruby - '-with-mysql-dir='C:/Program Files/MySQL/MySQL Connector C 6.1 6.1.2/'One pitfall to be aware of is that I changed the backslashes to normal slashes (/). I've tried the same procedure with backslashes and it didn't work.The installer already includes the C connectors for MySQL at MySQL Connector C 6.1 6.1.2 directory.
