Since the introduction of NAV 2016 the Windows Client is now also 64 bit just like the NAV Server. When you install the ‘Role Tailored Client’ from the NAV DVD you will now get 2 Windows Client executables:
- 32 bits version: C:\Program Files (x86)\Microsoft Dynamics NAV\90\RoleTailored Client\Microsoft.Dynamics.Nav.Client.exe
Use this client if your NAV partner is using 32 bit COM or .NET Components or of course if your system OS and hardware is still 32 bits…
- 64 bits version: C:\Program Files (x86)\Microsoft Dynamics NAV\90\RoleTailored Client\Microsoft.Dynamics.Nav.Client.x86.exe
If your OS is 64 bits then the 64 bits Windows Client will start by default. It’s obvious of course that the 64 bits client is the preferred client to use in order to utilize more memory (more than 4096 MB) for heavy reports for example.
