Microsoft are enforcing the usage of newer signing
certificates (SHA256, instead of SHA1). Because of that, a warning is shown
when downloading MSI files using Internet Explorer or Edge (Figure 1).
This warning can safely be ignored, if you obtained the MSI files from our website (http://www.telerik.com).

We are currently working on fixing the described issue.
Thank you for your understanding.
