For those having problems telling the Autolauncher where The Sims is located, go to your documents folder and find "Jagid's Sims 3 Autolauncher.ini." If it does not exist, feel free to create one manually.
The first thing the launcher does is look for its settings saved during the most recent setup session. You can avoid running setup by typing the values into the file manually. Here's a copy/paste of my file:
----------
[Launcher Play Button]
Mouse X Coordinate=115
Mouse Y Coordinate=260
[Load Game Play Button]
Mouse X Coordinate=833
Mouse Y Coordinate=916
Pixel Color=0x441B00
[Launcher File]
Path=D:\Games\Origin\The Sims 3\Game\Bin\Sims3Launcher.exe
[Pause Border]
Pixel X=2
Pixel Y=454
Pixel Color=0x9C0E0E
----------
You can see all the data is stored there. Feel free to edit it directly if setup isn't working for you.
Also, the app is using your windows environment variables to find your documents folder, even if you've customized it (mine is on my data drive, "D:" in a common folder where I store all the user data that I regularly back up). So when it looks for the INI file, it will always be looking in whatever folder you have designated as your root documents folder.
I have no idea what would happen on a mac, so I can't speak to that.
Also, depending on Windows version and security settings, it's possible you may need to run the Autolauncher as an admin. I seriously doubt it, though. It only accesses your documents folder and it clicks stuff for you. The system shouldn't really see it as a threat.
On the other hand, some Autohotkey scripts and compilers have had false positives on various virus scanners I've used over the years. You may want to check your virus scanner as well.
Also, I am told you can have Showtime remember your login data, so please do so.
If there is a consensus that the app clicks launch too quickly or does other weird things that I could fix, I'll edit the timing. I can even alter the script to allow custom timing per user to account for faster and slower machines. Just let me know.
Hope that helps!
