When working with a newly created Rails application on Windows 7, you might encounter an error message stating "193: %1 is not a valid Win32 application" upon accessing database-related pages.

To resolve this issue in Rails 2.3.2:

1. Navigate to the following URL: http://instantrails.rubyforge.org/svn/trunk/InstantRails-win/InstantRails/mysql/bin/
