I am trying to install 2.3.4.2 under medium trust using MySQL.  I have successfully installed earlier versions of Mojo so I think I have all of the configuration changes properly made for this install.  However, here is what I get when I try /setup/default.aspx.  No errors, just these messages.

.....

Probing system...
File system permissions ok.
MySQL database connection ok.
database permissions are sufficient to alter schema.
database initial schema needs to be created.
This site appears to be running in a secured environment using Medium Trust policy or at least lower than Full Trust.
In order to use MySQL under Medium Trust, The MySQL Connector for .NET must be installed in the Global Assembly Cache on the server. If you see a SecurityException in the error message then the Connector is not installed. You can download the MySql Connector for .NET from here: http://dev.mysql.com/downloads/connector/net/5.0.html

Note: This page shows some information that is helpful during setup and upgrades but for security it would be best not to show any information when the system is up to date. You can disable setup and suppress all information on this page by setting DisableSetup=true in Web.config. When you need to upgrade, you can set this back to false. If you are logged in as Administrator setup will run and you will be able to see this page even if it is disabled in Web.config so you can easily leave it disabled and just login before upgrading. But if you are not logged in you will need to enable setup in Web.config.

Again, no errors so I don't know where to start looking.  Any ideas?

Thanks!

That was it Joe!  Don't know how I missed that in the Readme file but I did.

Thanks for the help!
