VuGen can't open browser

Hi all,

i am new in VuGen, i want to prepare new script. i try to do all the steps after, selecting web(click and script) protocol.

i am trying to start recording the url, the record tab opens and i push the start recording button, but vugen can not open the web browser.

so, i open web-browser by my self and this situation effects the next step which is verifying replay. when i start replay all the time it returns fail which is

' invalid schema (not" http:/https:") in URL ="Please enter the initial URL here " [Msgid : MERR -32999]'

also, Occur at : Action.c(4) Code: -32999

What am i suppose to do ?
How can i fix this error ?

Best Regards
