script won't run a section of code - autohotkey

Question

I have this small script that is supposed to open up an app and type in some letters. However, for some reason the script won't run a section of code. It gets up to winMaximize and then stops. But if the app is already open then the section DOES run?? Not sure if I'm doing anything wrong, ideas?

By ommitting any wintitle parameters, you are calling winactivate and winmaximize on the "The Last Found Window". I think winMaximize simply doesn't execute because there was just no found window (it is called "the last found window", and not "the window which was found last, or maybe it wasn't").
Afaican see, your stack trace is
>
> IfWinNotExist, ahk_exe photoscan.exe ; does not exist. -> last found window: NONE
> RunWait, "C:\Program Files\Agisoft\PhotoScan Pro\photoscan.exe"
> ; still: last found window: NONE
> WinActivate / WinMaximize ; called on NONE
Not sure why winActivate terminates though. Either way, if you add ahk_exe photoscan.exe to winactivate and winmaximize, you should be fine
