How to associate a protocol with a program?

[Atanas Dyulgerov]

I would like to associate TEL protocol handler with a specific application installed on my Windows 8 system.

I go to "Associate a file type or protocol with specific program" tool in Control panel and see that TEL is already associated with Google Chrome from some reason.

I click Change Program and I see no viable options there.

Then I go to "Set a Default Program" tool and I do not see my application there in the list (it is installed property):

Anyway, I click on Google Chrome and then on "Choose Defaults for this program". I see the TEL protocol checked but I cannot uncheck it???
