RUN BROWSER(Internet Explorer) is not available in TestComplete v14.71.275.7 x64

Currently I am using TestComplete v14.71.275.7 x64 to create my automated web test cases, but I notice that RUN BROWSER(Internet Explorer) become suddenly unavailable and I don't know what happen.

Initially upon installation of the testcomplete I don't have this issue. 

Do you have a fix for this one? 

Thanks in advance.
