====== Installation ======

Sift runs most effectively on computers with the most CPU, RAM, and Network Capacity available. Like most software, the lower the capacity of the computer, the slower the reaction time of the program will be.

Sift can be operated on computers running Windows Vista, Windows 7, 8 and 10. At this time Sift is not compiled for operating systems other than Windows. Sift is designed to run on 64-bit computers.

  - When the completed dialogue appears Sift has been successfully installed on your computer. If you leave the checkbox selected Sift will be opened automatically, after you click the finish button.

===== Activation / Deactivation =====

You will need to activate sift before using it. Once Sift is activated, you will not need to repeat these steps again unless the program is deactivated. Each of the licensing key you purchase can only be used on one computer at a time. If you wish to use the licensing key on another computer you will need to deactivate Sift on the computer using that licensing key before using the licensing key to activate sift on another computer.

==== Activation ====

Sift cannot be used until it has been activated.

  - If Sift has not been activated then at the end of the installation process the activation Dialogue will be opened in order to allow the licensing process to begin.
  - You will be asked to enter you licensing key into the text field. It is a string of five sets of four numbers (ie. ####-####-####-####-####) which is normally e-mailed to you when you initially purchase Sift. The number can also be found on the [[http://www.has-motion.com|Has-Motion website]] when you login to your customer's download page. If you Cancel the Activation dialogue then Sift will close without being activated.
  - When you press Activate on the Activation Dialogue, the "Activation Complete" notice should appear.

NOTE: If you are not connected to the Internet the first time you start the program, or if you enter an invalid key you will get a message with key system information. First ensure you entered the key correctly if so, you can manually activate a license from the downloads web page (from the list of activated systems section), or you may copy the entire message in the dialog box and e-mail it to support@has-motion.com

NOTE 2: if you receive the "Previously Activated User" notice then the license is already in use and you will either have to deactivate it on another computer or purchase an additional license.

==== Deactivation ====

In order for a Sift license to be used on another computer, it must first be deactivated on the computer it is currently being used on.

  - On the tool bar select help -> about
  - On the about Dialogue Box click on the Deactivate button at the bottom right
