Question Status


Hi there!

We are cuurently expanding our Navision environment by adding the webclient. The WebClient is separated from the navsion server. Now I've got the following error:

The client version does not match the server version. You can only connect to a server with a matching version.

Client version: 9.0.46621.0

Server version: 9.0.47256.0

The problem is that both of these servers are running the same version (CU 10 | 9.0.46621.0) None of the servers we are operating right now are using CU13 9.0.47256.0.

Are there any solutions to this problem?

Thank you in advance!


You're using a different minor version of binaries between the server and the client. You need to install the web client bits by using the same package (DVD) used when installing the server part.

9.0.47256.0 is NAV 2016 CU 13 while 9.0.46621.0 is NAV 2016 CU 10.

Thats the problem. They are both using the exact same versions of NAV. Here are screenshots of both the web client and the NAV server:

MS NAV WebClient:


MS NAV Server:


As you can see. Both of these servers have got the same versions installed.
