Hi Subhashis,

Is the DLL in the folder?

Is the dll unblocked?

3

Hi Sander,

Yes DDL under the that folder and its unblock also .

4

For testing purposes only could you change the NAV service account to a admin account?

It will show if it is rights or something else

5

Yes we did that also , But no we got the same error .

6

Have you tryed importing a clean (From Product DVD) page 46 - Sales Order Subform and compile NAV?

7

This error came from standard NAV database

8

Did you re-compile all objects (or list of objects which linked with page 46)?

I so same error when I had problem with “linked page error”

9

Yes we did it.

Hi All ,

Thanks for suggestion. At present this issue is resolved .

Still root cause is unknown for this case , we create new VM for NAV app server then able to run the client. One thing confirm that It had nothing to do with permissions or Object Compilation.

I suspect that some windows patch causing this issue but not sure …

Thanks

Regards
