1.2.2
I recommend a fresh install of the latest version. Since the last update pyinstaller has changed the file structure, so while it shouldn't cause any problems, you will end up with a bunch of duplicated files if you care about storage space.
The easiest way to go to the file location is to open the program and from settings open the macro folder. copy your macros if you want to keep them, then exit that subfolder and delete everything in the AutoClicker&Macro folder. Then run the install.
