Many apps do, but they usually provide an installer because it is more convenient. It is a single executable package which installs the application in the proper place (under Program Files if the application is half-ass decent) and adds a shortcut to the Start menu.
Compare this to the folder method. You have to download a compressed archive, extract it, drag it to the proper folder, and create a shortcut (or alias or symbolic link) to the proper executable or executables (if the application has more than one program, such as a game and a level editor) in the proper location.
Executable installers are generally very easy to work with:
- Click on download link
- Click "open"
- App downloads to temporary location (WWW cache)
- When download is complete, installer automtically opens
- Click next a few times, click "I agree", click finish
- App is installed
This works 98% of the time.
Second Life has been hapily using NSIS -- featuring Super-PIMP(tm) technology -- for 3 years. We played with just about all of the different installers and settled on NSIS because it generated by far the fastest installs and also created the smallest files. Throw in the fact that it was incredibly easy to use and you had a winner. We haven't switched over to 2.0, though.
