Using Chromium instead of Chrome for web testing

Hi,

I'm using TestComplete for automating tests. Clients of my company will use Chromium to use our product. I've tried to install it on my PC but I can't select this browser in TestComplete because Google Chrome is always opening. If I uninstall both browsers and then install only Chromium it works fine, Chromium is being opened as I wanted, but then when I install Chrome, TC always selects Chrome. Is there any way to select which browser will be used by automated tests? Changing the version of the browser doesn't help at all. And reinstalling them over and over again is time consuming and uneffective.

In TestComplete 14 it always choosed most recent installation which was Chromium, but in 15 it always chooses Chrome by default.
