I have a new rails application which I have created under Windows 7 by going into a directory and typing “rails newapp”. The creation went fine, and when I access the root page, all is well. However, when I try to access a page that would access the database, I get this:

193: %1 is not a valid Win32 application.

In the developer.log. Mysql is running fine on my machine, and I have other applications which I have running in here in other directories, it’s just this one that doesn’t work. Any thoughts?

    Here’s the answer that worked for me. Turns out it was an issue of x64 vs. x32 issue and Rails 2.3.2.

    The answer I got from here (http://osdir.com/ml/RubyonRailsTalk/2009-06/msg01775.html):

    In case anyone else has the same
    problem after a lot of struggling on
    my Windows XP x64 machine, with MySQL
    5.1.30 (x64) and Rails 2.3.2 installed, this above suggestiong
    helped me.
    Download libMySql.dll from here (http://instantrails.rubyforge.org/svn/trunk/InstantRails-win/InstantRails/mysql/bin/)
    and putting it in ruby\bin solved the
    problem.
