Pro tips.

Multiply Dynamics NAV servers.
If the site is an environment with multiply applications servers, the first part (Placing the Gantt.exe file) must be done on every server.
Gantt.exe location.
You can change the location of the Gantt.exe file, in the C:\NavGantt (Server) folder.
However, I you chose to do so, the NAV program must be slightly changed – edit the source code of the object.
Security (Server)
The read permission for the Gantt folder and Gantt.exe file doesn’t have to be everybody.
The NAV service, and the users must have read access to the file, so read access for the NAV service account, and users will do.
