The steps for installing Extender can be different depending on if you are installing in a Microsoft Dynamics GP Environment where it has never been installed or you are installing into an environment that currently has a previous 2013 or 2015 build of Extender installed.

Please be sure to follow the appropriate steps.

If you are on a previous release of Extender and Microsoft Dynamics GP such as 2010, you are going to need to do an intermediary update to Microsoft Dynamics GP 2013 or 2015.  Please review the upgrade steps in that releases manual for more information on the process for the appropriate build.
