Nav 2009 is out of support so you will not get any official statement about the comparability with Windows 11.

So you should start to look into doing an upgrade to a supported version.

But maybe someone have some experiences with Nav 2009 and Windows 11.

Hi, I've used it on Windows 10 with no issues. (maybe for a short period of time)

I tried to find the System Requirement of NAV2009 in Microsoft Docs, but unfortunately I couldn't find it.

The following is the most complete version I found, so if you want to use NAV2009 stably, it is better to stay on Windows7.

Hope this will help.

Thanks.

Hello,

Running NAV 2009 on Windows 11 has an error message [Internal error 101 in module 47].

Has anybody encountered that before and knows why it happens?

Thanks in advance.

It seems a language problem, it's OK when use [English] language to run NAV 2009,
I replaced the fin.etx and fin.stx files in the CHT directory, and it has been executed normally.
Thanks very much.

We were running NAV2009 SP1 on Windows11 without any issues for almost a year.

But now, the Windows 11 22H2 update seems to have broken something.

The NAV client (SQL) starts normally, you can do File>Database>Open and enter the server name, the database and your credentials, as before.

But then the client tries to connect and nothing happens. After 30 seconds, you get "The server could not be found".

This only happens on PC's that were updated from Win11 21H2 to 22H2.

Any similar experiences? Or better, any resolution for this problem?

Thanks!

I am having an issue connecting via RTC Client for NAV 2009 R2 on WIn11 recently.

It was previously working fine before.

The error is SSPI failed, see inner exception.

I suspect a windows update on my PC as well.

The RTC client works fine on Win 10 clients.

Have you been able to fix your issue?

No, unfortunately not.

It works fine on Windows 11 21H2, but no longer after the 22H2 feature update.

I managed to make NAV 2009R2 function correctly with Windows 11 22H2 by disabling credential Guard via GPO.
