    Download link in KB article does not work… “Sorry, the page you requested is not available”

  2. guido robben says:

    This updates doesn’t correctly set the OptionString of field 4 – State of Table 2000000120 – User. It leaves the OptionString at “Geactiveerd,Uitgeschakeld” insetad of “Enabled,Disabled”. This causes errors when opening pages, because it cannot validate Enabled to a option.

  3. Thomas Lehle says:

    Download link in KB article still does not work.
    I get the same Error as Kamil Sacek.

    When you try to execute an object from whitin the development environment you get an error from windows : Microsoft.Dynamics.Nav.Client has stopped working

    a workaround is to execute the development environment with amministrative rights

    Someone have the same issue?
