The contents of the ZIP file should be extracted to a suitable location on your PC, preferably a dedicated folder created for the purpose. The Colour Recovery application is run by executing the file 'colourrecovery.exe' (you can create a shortcut on the desktop or in your Start menu if you prefer). If installed in a 'protected' location it must be run at least once with Administrator privileges; thereafter it may be run by an ordinary user.
The Colour Recovery application should run on any Windows XP, Vista or Windows 7 PC, but the faster the machine the better! You can run multiple copies of the program, each processing a different source sequence, to take maximum advantage of a multi-core processor or multiple CPUs, if available.
The program requires 'QuickTime for Windows' to be installed on the PC; this can be downloaded free of charge from Apple's web site. Even if QuickTime is already installed, you are advised to update it to the latest version to ensure it is compatible with the Colour Recovery application.
If you want to try running the program, and have no access to suitable source material, a 'simulated' Film Recorded frame is here.
Note that the public release versions are made available for experimentation and evaluation purposes only. Their use for commercial applications (e.g. DVD production, broadcast or entering of material into the archive) is prohibited.
