Running 32-Bit Microsoft Dynamics Windows Client on 64-Bit Windows
On a 64-bit version of a Windows operating system, a 64-bit version of the Microsoft Dynamics NAV Windows client runs by default. The 64-bit version is suitable for most installations. It has an advantage over the 32-bit version because of its memory allocation capabilities, which is especially useful when running several large reports. However, if an application uses 32-bit components, such as COM technologies and 32-bit .NET Framework components, these components will not work in the 64-bit version of the Microsoft Dynamics NAV Windows client. In this case, you must run the 32-bit version of the Microsoft Dynamics NAV Windows client.
Run the 32-bit version of the Microsoft Dynamics NAV Windows client
By default, the Microsoft Dynamics NAV Windows client is started by running the Microsoft.Dynamics.Nav.Client.exe file. This file runs the 64-bit version of the Microsoft Dynamics NAV Windows client on a 64-bit Windows operating system and the 32-bit version of the Microsoft Dynamics NAV Windows client on a 32-bit Windows operating system. The file is installed by the Microsoft Dynamics NAV Setup, where the default location is C:\Program Files (x86)\Microsoft Dynamics NAV\90\RoleTailored Client folder. In the same location, Microsoft Dynamics NAV Setup also installs the Microsoft.Dynamics.Nav.Client.x86.exe file, which you use to run the 32-bit version of the Microsoft Dynamics NAV Windows client.
To run the 32-bit version of the Microsoft Dynamics NAV Windows client, do any of the following:
Run the Microsoft.Dynamics.Nav.Client.x86.exe file directly from the installation folder or create a desktop shortcut.
Rename the Microsoft.Dynamics.Nav.Client.exe file to Microsoft.Dynamics.Nav.Client.X64.exe, and then rename the Microsoft.Dynamics.Nav.Client.X86.exe file to Microsoft.Dynamics.Nav.Client.exe.
This sets up the 32-bit version to run from the Microsoft Dynamics NAV link in computer's Start menu and from the Microsoft Dynamics NAV Development Environment.
If you are installing the Microsoft Dynamics NAV Windows client on multiple computers and you want them all to run the 32-bit version, then on the Microsoft Dynamics NAV installation media (DVD), you can rename the .exe files as described in the previous bullet.
