  • Question

  • Hi,

    I have a machine with both Visual Studio 2010 and Visual Studio 2013 Update 3 installed. Earlier I was having only Visual Studio 2010 on my machine and I was able to build my VSTO Add-In successfully. But after I installed Visual Studio 2013 Update 3, I am not able to build my Add-In at all. I get this error always:

    The "FindRibbons" task could not be loaded from the assembly Microsoft.VisualStudio.Tools.Office.BuildTasks, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.
    

    I searched about this and someone suggested to update "Version=10.0.0.0" in Microsoft.VisualStudio.Tools.Office.targets file (Location in x64: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\OfficeTools) to "Version=12.0.0.0". I tried this, but it didn't worked for me. I tried reinstalling VSTO 2010 and Visual Studio 2010 as well. But nothing worked. Is there a way to get rid of this error or I should uninstall Visual Studio 2013 Update 3 to make it work?

    Thanks in advance.

  • Hello Prasad,

    Try to install Update 4 for VS2013 :)

    Did you try to create a new add-in in Visual Studio 2010? Does it work without errors?

    If not, I'd recommend re-installing or repairing VS2010 on the machine. Hope it helps.

  • Hi Eugene,

    Thanks for the reply.

    Yes I tried creating a new Add-In and that also failed.

    I have not tried installing Update 4 for VS2013 which I can try and confirm.

    Thanks

  • Hi Prasad,

    Did install update 4 for VS2013 work for you? Did you open your project under VS2010 or VS2013 get this error? I suggest you try to uninstall all versions of Visual Studio, then install them back in ascending order (VS2013 with Update4).

    Best Regards,

    Edward
