I published my .net application using ClickOnce, and all my users get the following error message on trying to open the program:
"Unable to install or run the application. The application requires that assembly Telerik.Windows.Data Version 2012.1.215.40 be installed in the Global Assembly Cache (GAC) first".
The version I actually use in my application is NEWER than the one mentioned in the error message. I also don't have this problem on my machine which I use to develop the application. I wonder why it is looking for the older version of the dll. I can't find where it is referenced by my application.
Could you please help me on this?
