I'm trying to do a clean install of 4.5.0b. I get all the way to step 7 and I get the following error...

----------------------------------------------------------------------------------------------------------------------
Creating Sugar configuration file (config.php)

Creating Sugar application tables, audit tables, and relationship metadata...

Fatal error: Cannot instantiate non-existent class: mysqlmanager in /.../include/database/DBManager.php on line 173
------------------------------------------------------------------------------------------------------------------------

Have did a CHMOD 777 to EVERYTHING just to make sure it was not a permission problem.

Here is what I have...
PHP: 4.3.9
Mysql: 4.1.20
Apache/2.0.52 (Red Hat)

Does anyone know what I can do to correct this?

Kind Regards,

Ed
