    Courier Breaks Contour

    After installing Courier (2.50.1), I get an error message when I try to create a new Contour (3.0.18) form or view an existing Contour form in Umbraco 7.2.6:

    Licensing Error

    For the search engines, that error message is:

    System.MissingMethodException: Method not found: 'Void Umbraco.Licensing.UI.InjectTrialMessage(Umbraco.Licensing.Validator, System.String, System.Web.UI.Page)'.

    Seems like the version of Umbraco.Licensing.dll added by Courier is incompatible with the version of Umbraco.Licensing.dll used by Contour.

    Has anybody who has encountered this found a workaround (I'm considering trying a Contour upgrade)?

    Hi Nicholas,

    I can see that there have been an issue before where Courier Breaks Contour. Maybe you could try what Paul describes, and if it dosenĀ“t solve your problem the I think you should report the bug again on

    Hope this helps,

    Hmm. Paul didn't describe how to fix it. He said:

    The latest licensing dll has fixed this discrepancy.

    I have the latest version of Courier, so I'd think it would come with the latest licensing DLL and the issue should be fixed. Maybe I need to upgrade to the latest Contour too for the issue to be fixed. Will give that a try.

    I haven't seen this issue for some time so I assume it's just a discrepancy in terms of the specific versions you have and the licensing dll version.  You can find the most recent here  The licensing dll was updated for Forms, and we've been shipping that version with Courier (for v7) as well.

    Installing the new version of Contour (3.0.27) seems to have fixed it (broke some other stuff, but luckily I've seen those errors before and was able to handle them quickly).

    Actually, it appears the latest Courier (2.50.1) breaks even the latest version of Contour (3.0.27). I installed Courier to a website that had the latest Contour, and I got the same error. The fix was to revert the Umbraco.Licensing.dll to the version Contour had before Courier overwrite it.

    Not sure if this is a Courier or a Contour issue, but they aren't playing nicely together.
