There might be a simple solution but I wouldn't be the one to figure it out..

I tried to install and got this error:

Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of module_invoke_all(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file in C:\wamp\www\drupal\sites\all\modules\ubercart_marketplace\mp_products\mp_products.module on line 219

If your php config does not allow pass by reference (and/or you do not wish to enable in php.ini), you can safely remove line 219 from mp_products.module. This is a hook that has a potential future use to some individuals and its quality and removal will be assessed for the next Marketplace release.
