Can't open browser

Hello. I am new at Katalon Studio and may be my question is pretty nooby, please forgive me:)

I am going to try a very simple test case - just open my browser.
So I had already created a simple project, changed in “Window->Katalon Studio Preferences-General->Web Browser” default browser to “Chrome”.
Than I created a Test Case and add only one action “Open Browser” with blanck page
Than I click at “Run” and expected that a new blank page would be opened
Actually I had an enormous stack of errors

What I need to know:
1. What should I do for permanently changing my browser to chrome? (see for “09-12-2018 06:57:38 PM - [INFO] - Starting ‘Firefox’ driver” in console log)
2. How could I solve problem with path to webdriver?

Hi Valeriy

Please change default browser from:
Window -> Preferences -> General -> Web Brower

This message tells that you actually selected Firefox driver while you meant to use Chrome driver.

To me it seems you do not have Firefox Browser installed.

Please check exactly, what I had wrote above
“So I had already created a simple project,** changed in “Window->Katalon Studio Preferences-General->Web Browser” default browser to “Chrome”.”
**
Now I try to run test case in Chrome manually and faced against another error

Starting ChromeDriver 2.41.578737 (49da6702b16031c40d63e5618de03a32ff6c197e) on port 14418

Only local connections are allowed.
Please, see that it is the latest chromedriver so dont recomment to update it

Upd. My computer is beyond corporate proxy, but I already set it in preferences
