delphi - TGMMap Accessed Denied -

i using gmlib v1.5.0 , seem having strange error when using gmmap component.

i created small project in delphi xe7 following setup in attempt resolve error: tform, twebbrowser , tbutton , tgmmap. tgmmap set use twebbrowser browser. application accessing web via proxy server. on tbutton click event have added following code:

procedure tform6.button3click(sender: tobject);  begin  gmmap1.active := true;  gmmap1.requiredprop.zoom := 3;  end; 

on tgmmap afterpageloaded event have following code:

procedure tform6.gmmap1afterpageloaded(sender: tobject; first: boolean);  begin  if first  gmmap1.domap;  end; 

the app works on other computers on our network range windows xp windows 8, except one. on specific machine running windows 8 whenever click on button execute gmmap1.active := true; code access denied error , no further errors, google map not displayed in twebbrowser component either. have disabled antiviruse still no luck. if execute following code webbrowser1.navigate('http://www.google.com/maps'); using twebbrowser application works fine seems when using tgmmap component.

there possibility 1 pc may issue need confirmation. has else had error? gmmap trying access being denied system?

start->control panels->network,internet-> internet options-> click card security , decrease security level (internet,middle high). luck..
