I have written a code to automate installing of applications in windows. But it doesnt work when it encounters radio buttons. Plz help. The code is below:

#! usr/bin/perl
#use Win32::Gui;
 use Win32::GuiTest qw(:ALL);
 use strict;
 
my $window = FindWindowLike( undef,"[Install*.*|*Setup.*]","" );
while(1)
{    
        for($window) 
        {
            SetForegroundWindow($window);
            
            my @hwnds = GetChildWindows($window);
            foreach(@hwnds)
            {
            SetForegroundWindow($_);
            my $var = GetWindowText($_);
            print "shayak";
            print $var;
            my $class = GetClassName($_);
            print $class;
            #my $child = GetChildDepth(GetDesktopWindow(), $_);
            #print $child;
            if ($class == ["*RadioButton"])
            {
        
                my $id=GetWindowID($_);
                print $id;
                #CheckButton(GetWindowID($name);
                if (WMGetText($id)==(["*agree*" ]or ["*accept*"]))
                {
                    CheckButton($id);
                }
                else
                {
                    SendKeys{"TAB"};
                    SendKeys{"UP"};
                }
            }
            #PushButton("Next" or "Agree" or "Install" or "Yes" or "Fi
+nish" or "Done");
            SendKeys("~");
            }
        }
}
