Inside your installation of One-Click Installer, there is a gems
folder:

Example for ruby installed in C:/Ruby

C:/Ruby/lib/ruby/gems/1.8

1) Use Explorer to browse to that folder and copy it's contents into a
safe place.

2) Uninstall current One-Click Installer

3) Installer newer version (you pick one, I suggest stick to 1.8.6
with patches).

4) Copy back your contents in the same folder.

5) Done.

It should work, verify it for your self :-D
