Check if exist if not download/andrun

[MrCoolGuy]

Current Code is

What i'm trying to do; is check if file exist or directory exist then if so display a message... and if it doesn't exist then download/install a program the thing is I have more then one button named different things. and i got this almsot down.. I do.. I just can't figure it out


I had this originaly (without checking the file/folder)

bRadioValue = RadioButton.GetChecked("fddy");
if bRadioValue then
	-- C
	File.OpenURL("http:// blah balh.com", SW_SHOWNORMAL);
end

and I try to add this (I searched the forum and got something like this

bRadioValue = RadioButton.GetChecked("Firewall32");
if bRadioValue then
 Folder.DoesExist (_ProgramFilesFolder .. "\\Java"); Dialog.Message("Formating Has Been Scheduled for Next Restart..", "Yep; You got that right we are formatting your data oh shoot,    Say good bye to your data.. Yes Yours.....    Just Kidding, Another Installation is detected.. I got ya.. ", MB_OK, MB_ICONEXCLAMATION, MB_DEFBUTTON1);
else 
	File.OpenURL("http://download.jacobkilgore.com/86.exe", SW_SHOWNORMAL);
end

I'm learning.. Quickly I should say;

Could anyone shine some light on this?

Ah! I wish i could just use batch

if exist button1checked goto HI
if not exist button1checked goto HI1
:HI
If exist %programfiles%\Java msg * You already have it
else start http://www.google.com/hi.exe
:HI1 (this is here to skip above two lines but continue with the script.)

if exist button2checked goto HEY
if not exist button1checked goto HEY1
:HEY
If exist %appdata% msg * You already have it
else start http://www.google.com/hey.exe
:HEY1 (this is here to skip above two lines but continue with the script.)




Selects RadioButton A:
Clicks on Download
Check if java folder exists; if not then go ahead and download .exe if does exist then display message
