QuickTime 3 is available as a single self-extracting executable file of 6.8MB. You can choose to download it to a specified location (do remember where you put it!) or to run the installer directly from the Apple site (the better choice if you have a fast internet connection). It is easiest to save the file to your desktop directory and then, double-click on the file to run the installer program, if you are new to downloading programs like QT 3.

Applications written for Windows 3.1 are 16 bit applications. QuickTime 2.1.2 16-bit was written for Windows 3.1. If you install an application that was written for Windows 3.1 and that application uses QuickTime, that application will need QuickTime 2.1.2 16-bit.

QuickTime 2.1.2 32-bit
Applications written for Windows 95/NT generally take advantage of the 32-bit nature of Windows 95/NT. QuickTime 2.1.2 32-bit was written for this environment. Applications written for the 32-bit nature of Windows 95/NT that use QuickTime will need QuickTime 2.1.2 32-bit.

QuickTime 3
QuickTime 3 is an entirely different and new Application Programming Interface (API). Applications written for QuickTime 3 do not work with QuickTime 2.1.2 (either 16- or 32-bit). They will require QuickTime 3 specifically. The QuickTime 3 API for Windows 95/NT is a port of the Macintosh version of QuickTime 3.

Here is a scenario that requires all three versions of QuickTime on one computer:

You have an application (such as a game or other media rich application) which was written to Windows 3.1 16-bit and uses QuickTime. (You must have QuickTime 2.1.2 16-bit installed on your system.)

You have an application which was written as a 32-bit application using QuickTime. (QuickTime 2.1.2 32-bit must be installed on your system.)

You have an application written for QuickTime 3, such as the video/audio files on this site. (QuickTime 3 must be installed on your system because the QuickTime 3 based application will not recognize earlier versions of QuickTime.)

This product is available four different ways. Each method of obtaining this update will provide you the exact same software:

If you choose (a) or (b), download this self-mounting file to your hard drive and then double-click it to uncompress and mount the file on your desktop. Please read the documents included in this file before installing the software.

If you choose (c) or (d), download all 5 parts to your hard drive and then double-click on the first part to uncompress and mount the file on your desktop. Read the documents included in this file before installing the software. You may wish to download the 5 parts instead of the single self-mounting file if you are a using a modem connection. Download all 5 parts to your hard drive and then double-click on the first segment to uncompress and mount the file on your desktop. You do not need to rejoin the parts, but all the parts must be in the same folder. Please read the documents included in this file before installing the software.

All of the Macintosh files available from Apple Software Updates are encoded in both MacBinary (.bin) and Binhex (.hqx) formats for transmission over the Internet. MacBinary is smaller and will download faster. Binhex is for customers who are connecting to the Internet via older systems. We suggest you try the Binhex version.

Once you have downloaded these files, they must be decoded before you can use them. StuffIt Expander is included with many web browsers and will decode files once they are downloaded. Fetch is an FTP client that can decode files as they are downloaded.Check the preferences of your client software or StuffIt Expander to see where those applications place files on your hard drive once they have been decoded.

Once the files you have downloaded have been decoded, they will be one of the following types:

	Self Extracting Archive (.sea): Double-click on the .sea file to decompress its contents. The result will be a file or folder of files. Many of these .sea files contain Disk Copy version 4.2 images.
	Disk Copy self mounting image (.smi): Double-click on this file to mount the image on your desktop. You can then review any read me documents or launch installers.
	Disk Copy version 6.x image (.img): Double-click on this file to launch Disk Copy, which will mount the image on your desktop. You can then review any read me documents or launch installers.
	Disk Copy version 6.x image part (.part): Disk Copy images that are available in multiple parts consist of one .smi file and one or more .part files. All of these files must be located in the same folder. Double-click on the .smi file to mount the image on your desktop. You can then review any read me documents or launch installers.
	Disk Copy version 6.x DiskScript (.scr): Some software is available as one or more Disk Copy images with a corresponding DiskScript, which automates Disk Copy functions. All of these files must be located in the same folder. Double-click on the .scr file to mount the image or images on your desktop and automatically launch installers.

If you have System Software 7.0.1 or higher, you will need Disk Copy 6.1.3 to work with disk images.

If you have System Software 6.0.x or 7.0, you will need Disk Copy 4.2 to work with disk images.

The de-hexed files are .sea or self extracting files, and by double-clicking them, they will expand to disk image files. The disk image files are then ready to be made into floppy disks using Disk Copy 4.2 or Disk Copy 6.1.3.

The QuickTime 3 plug-in should configure your browser to open our video and audio files automatically.  If this is not occurring after a successful installation, then check your plug-in configuration window to make sure that the .mov files are set to be opened by QT 3.0.
