Task scheduler - "How do you want to open this .au3 file?"

[Armando817]

I am running Windows 10. I have an AutoIt script (all it does is display a msgbox) that I want to start at a certain time of the day using the windows task scheduler. When the task scheduler starts the script I get the "How do you want to open this .au3 file?" dialog (see attachment). I have the default program already set for .au3 scripts but I get the dialog no matter what. Any suggestions? Thanks.

Compile the script as an exe?  Or use the full path to autoit3.exe i.e.: C:\Program Files (x86)\AutoIt3\autoit3.exe "C:\Filename.au3"

Thank you, Subz. I compiled the script to an .exe and the task scheduler works fine.
