Installing unsigned driver

[Tripredacus]

No matter what I try (sending keys, using the mouse, etc) I cannot get Autoit to activate the "Continue Anyways" button that comes up when you try to install an unsigned driver. It actually installs the driver properly, but the Hardware Installation window opens and nothing happens. Here is the code I have for this atm:

FileCopy("\\server\install\all drivers\serial & parallel\lava serial drivers\lavaosp.inf","c:\windows\inf")
            FileCopy("\\server\install\devcon.exe","c:\windows")
            RunWait(@ComSpec & ' /c c:\windows\devcon.exe update c:\windows\inf\lavaosp.inf "PCI\VEN_1407&DEV_0110&SUBSYS_01101407&REV_00"')
            WinWait("Hardware Installation","")
            ControlClick('Hardware Installation', '', 'Button1')
            Sleep(4000)
            RunWait(@ComSpec & ' /c c:\windows\devcon.exe update c:\windows\inf\lavaosp.inf "PCI\VEN_1407&DEV_0111&SUBSYS_01111407&REV_00"')
            WinWait("Hardware Installation","")
            ControlClick('Hardware Installation', '', 'Button1')
            MsgBox(4096,"Install","Lava Serial Drivers installed. Click OK to verify in device manager")
            RunWait(@SystemDir & "\mmc.exe " & @SystemDir & "\devmgmt.msc")

Perhaps use Run() instead of RunWait() so the script can progress.
