Selenium IDE - MalformedURLException when running from command line

[jap...@gmail.com]

Hello,

I have created a test suite using Selenium IDE and I am trying to run it from the command line, but I get a "MalformedULException: unknown protocol: c" error. After i run the command, the browser opens and closes right after that. 

This is the command I use: 

java -jar selenium-html-runner-3.0.1.jar -htmlSuite "*firefox" "https://my.page.pl" "c:\projects\selenium\update_v_suite_old.html" "c:\projects\selenium\result.html"

and this is part of the log I see:

I use Selenium IDE 2.9.1, Firefox 49.0.1, selenium-html-runner-3.0.1, Java v8u112.

I'm not much of a programmer, so could anybody please help me in as simple way as possible?

Greetings!
