===== 4.5. Register a new add-on loader =====

Start SAP Business One and the add-on files are automatically loaded.

In general, for a Produmex WMS version upgrade it is not required to install a new version of the add-on loader. Consult with the [[implementation:general:compatibility_matrix|Compatibility Matrix]] and check if the installation of a new version is needed. The document describes which add-on loader version is required for the given add-on version.  

Note: It is possible to have multiple add-on loader versions installed on one server. 

(For more information on how to install the Add-on Loader see section [[implementation:wms:install_registeraddon|3.5. Register the Produmex add-on]].)

The process of performing a version upgrade is finished. Make sure that the company settings of your organizational structure are correct. 

The [[implementation:wms:install_adddb|next section]] describes the process of adding a new database to an existing installation.
