Dynamics NAV 2016 installation overwrites NAV 2015 Administration Tool
Dynamics NAV 2016 installs nicely side-by-side with Dynamics NAV 2015.
But, there is an issue after install Dynamics NAV 2016 with Dynamics NAV 2015 – Dynamics NAV Administration Tool 2015 doesn’t work anymore. If you open it, you will see this kind of error:
The reason that Dynamics NAV 2015 Administration Tool is starting Dynamics NAV 2016 is because of a registry entry. There is just one registry entry that is used for both versions which points to the assemblies that must be loaded.
The NAV Administration Tool is a Microsoft Management Console snap-in. This snap-in is started by the file “Microsoft Dynamics NAV Server.msc” which is in your RoleTailored Client folder.
The “Microsoft Dynamics NAV Server.msc” file is basically an XML file with an entry that points to and registry key.
The NAV 2015 and NAV 2016 Administration Tool both point to this registry key:

To import the file into the registry, by double click the save .reg file.
To edit the “Microsoft Dynamics NAV Server.msc” file (C:\Program Files (x86)\Microsoft Dynamics NAV\80\RoleTailored Client\) Right click and open with notepad and search the value BA484C42-ED9A-4bc1-925F-23E64E686FCE and replace to BA484C41-ED9A-4bc1-925F-23E64E686FCE
