This is to do with the config file prowin32.exe.config file, there should be a line of code present in this file as below:

<assemblyIdentity name="Telerik.WinControls.UI" publicKeyToken="5bb2a467cbec794e" culture="neutral" />
<bindingRedirect oldVersion="2019.2.618.40" newVersion="2020.1.113.40" />

If this is not in the file then please raise a new case online and reference the title of this article. and we can give you a different config file.

The location for this config is in the C drive/ progress/bin/ the file name is prowin32.exe.config.

Open this using the notepad to check.
