Hello, ATHIQ,

Thank you for writing.  

I would like to ask you to carefully check the references to all Telerik controls in your project and make sure that they are the same version considering the suffix as well (.20 or .40). Better yet, you can remove all references and add them anew by using the DLLs from your fresh installation. Delete the license. file. After that, you should rebuild your project, close Visual Studio and open it again to make sure that no references are kept in the memory by Visual Studio.  

I hope this information helps. Should you have further questions I would be glad to help.
 
Regards,
Dess

Hello, Jenny,

Thank you for writing.  

If you obtain such an error, this means that either the referred ddls in your project differ from the one in the license.licx file or you have installed a different version of the Telerik UI for WinForms suite. That is why I would recommend you to follow the described steps in my previous reply. If you are still experiencing the same problem, it would be greatly appreciated if you give us some more details about the used version of our suite, whether you have an installation or not, what is the available version in GAC. Thus, we would be able to assist you further. Thank you in advance.

I hope this information helps. Should you have further questions I would be glad to help.

Hi Everyone.

Thank you for reading this post.

This is very frustrating. I was running my program after installing visual studio 2019. Then I got another program from my colleague and while building the program I get the error message that Telerik.Win.Controls.UI could not load. 

I see that the .dll files are in the library.

What could go wrong?  Is it because of the VS 2019 version. But I was running the other old program in that same environment.

I appreciate your help.

Thanks,

Robi.
