As it turns out this is an unnecessary check, that we have already removed and will be part of the service pack that we are preparing. As a workaround you can just add the enviroment variables and this warning will cease to pop up.
I would like to apologize for inconvenience caused by this and to thank you for letting us know about this problem. Do find your Telerik points updated.
All the best,
the Telerik team
