Can anyone help :?: :?: :?:

Recently upgraded to Win 10 from Win 8 and now my RTC install of Nav 8 (39663) will not run.

The service appears to be started, port sharing is on but I keep getting the following:
The Server "DynamicsNav80" was unable to process the request. The application will close

Event viewer doesn't seem to help (or not when I google this problem), but here is the dump from event viewer.....

Server instance: DynamicsNAV80

Only results I managed to find were suggestions on duplicate keys, but I never got this on win8 with the exact same DB, and exact same NAV exe?

Any ideas where to look ?

Many thanks in advance

    From your description it sounds like one of the issues that are fixed in the upcoming CU for Nav 8. The underlying reason (in case you are interested) is that Win10 contains duplicate 3-letter language codes, and the code was not prepared for that.

    Hi Jens,


    So is this a regional settings issue in win10 or a captions issue in NAV ? (or both maybe?)

    It just so happens that I noticed something odd when I clicked on my Language preferences in the taskbar.... (check the screen grab in the attachment)

    Did this get resolved. I have a client that is trying to run the same build of NAV 2015 on a Windows 10 machine. The Service Tier is not running.

    This is not going to work, as at least Build 42951 (CU 12) is required for Windows 10.
