I am getting the same message from running the examples I received when installing the ASP.NET MVC version.  Should I put the mvc.dll to my paid for vs the one the example came with?

Hello bUb,

Yes, please use the Kendo.Mvc.dll assembly that came with the commercial product installer. Trial exceptions only appear when using the trial assembly. If you don't have a commercial installer at hand, please download it from "Your Account" > "Products & Subscriptions" at telerik.com.

I had to change the reference to kendo.mvc.dll by removing the examples kept in it's own solutions' folder and then add in the paid for dll by browsing to it.  Is there any easier way to go about this?

Hello bUb,

I think that is the easiest way for changing references to a dll. Another approach could be to copy the commercial dll and paste it directly where the reference of the trial dll points to, substituting the trial one. I am glad that you managed to resolve the issue faced.
