There's some questions I get asked practically every single day. So here's some answers.

How do I install Sonic 3 A.I.R.? (Windows)
Just download one of the ZIP files for either the stable or preview versions, and extract it to some location on your hard drive (e.g. on your desktop, or your documents folder, etc.). Now you can start the Sonic3AIR.exe there. That's all.

How do I update to a new version of Sonic 3 A.I.R.? (Windows)
It's as easy as installing the new version, preferrably to a different location than the old installation. Your existing save game data will be used by the new version as well, as it's stored outside of the actual game installation (see the game's Manual PDF for details).
After a quick check if the new version is working, you can safely delete the old game installation.

What to do when there's graphics issues with Sonic 3 A.I.R.?
Changing the renderer to OpenGL Software could help. If not, try switching to fail-safe mode. For instructions on that, have a look at the Manual PDF linked above.

What to do when the game just crashes on startup?
There's a known bug that certain USB devices (game controllers and others) can crash the game. So the first thing you should try is disconnecting all USB devices and start Sonic 3 A.I.R. again.
Another common problem is graphics driver issues. You should definitely make sure your graphics drivers are up-to-date. If you're at the latest drivers already, you can still switch the game to fail-safe mode, as described in the Manual PDF linked above.

Why can't I just use any Sonic 3 & Knuckles ROM?
Getting the Steam version of Sonic 3 & Knuckles and using its ROM is a clean, 100% legal way to get S3AIR running. Using just any ROM downloaded from somewhere on the internet is not. This project does not endorse piracy in any way.
Aside from that, there's also a hard technical requirement to use that exact ROM: S3AIR loads a lot of data directly from the ROM and expects all of that in very specific locations. Other ROMs than the Steam versions usually don't use the exact same internal layout, so reading anything from those would only produce garbage data that the game can't handle, so it would probably crash right away.
That's also why you can't just plug in a S3&K ROM hack and expect that to work with S3AIR.
