I have downloaded and run the example right now. I'm not getting any errors.

In top of the script Calculator and Notepad are opened. Can you see if these programs are opened. If not just comment out these two lines and open the programs yourself.

Add a check to make sure that the variable is an object, prior to using properties|methods

IsObj

you might need to add a loop to wait for it to be an object

Hi i've check in UIAWrappers.au3 and found that the script can not create object

func _UIA_Init()
;~  consolewrite("initializing")
    ;~ The main object with acces to the windows automation api 3.0
    $objUIAutomation = ObjCreateInterface($sCLSID_CUIAutomation, $sIID_IUIAutomation, $dtagIUIAutomation)
    If IsObj($objUIAutomation) = 0 Then
        msgbox(1,"UI automation failed", "UI Automation failed",10)
        Return SetError(1, 0, 0)
    EndIf

$objUIAutomation = 0 so it's not a object. Im using Autoit version 3.3.10.2. What should i do now?

What platform are you on? This should run from XP SP3 to Win 8. If you are on XP or Vista there may be a risk that the API isn't installed. See http://support.microsoft.com/kb/971513. Can you verify that UIAutomationCore.dll is installed on your system?

Hi, im using XP SP3. I've searched for UIAutomationCore.dll and found it in system32 folder, so i think it's installed

I have just tested on my old XP SP3. It works.

luckyluke, It seems as if UI Automation isn't working on your PC. You can try to install the UI Automation update in the link, and you can try to update everything on your PC with Microsoft Update, if you haven't done that.

Try example 1 or the simple spy example first. Some examples can be broken
