This is the full version guys, here are some instructions:
1) Once downloaded, extract the folder, to wherever you want. (I just kept it in downloads.)
2) Go into the folder, click on the icon named "sai-eng-pack-1.1.0" and install it, it should automatically be installed in "Program Files" as normal.
3) Once done that, go back into the downloaded folder, and right click, "run as administrator" on the icon called "sai.exe", click "ok" or "yes" depending on what comes up.
4) And theres your sai, now copy that file to desktop, or wherever you keep it as a shortcut, you must use that icon everytime, the "Program Files" sai icon is just the regular trial version.
Sorry if it doesn't work, but also let me know if there are any problems.
