Recently I installed the GB version of the Dynamics NAV 2009 SP1 Classic client directly from the CsideClient folder and was surprised to find the ENG folder absent after installation.

Why had it not been installed?

Between NAV 2009 and NAV 2009 SP1 the structure of the installation media has changed slightly.

Up until now the language folder could be found in ..\CsideClient\program files\Microsoft Dynamics NAV\60\Classic and would be installed if running setup directly from the ..\60\Classic folder:

With SP1 all localisation has been been moved into a new folder at the root of the installation media called Installers

The Installers folder contains subfolders with localized installers for the following:

• CSide
• Documentation
• OlAddin
• RTC
• Server

The upshot of this is that locale specific files will only be installed if you run the main setup executable at the root of the installation media.

You can however run the installers independently from the folders above if you need to.
