However, the reality is that we must first ensure that your system is setup and that you have installed Scratch on your system. ...
Downloading & Installing Scratch
- go to the Scratch home page
- click the Download link
- donate a small bit of money to the ongoing development of Scratch
- choose and download the right version of Scratch for your computer
- double-click on this file to install (or click from your browser's download area).
Second, as of the writing of this book, the following versions are all available here (http://info.scratch.mit.edu/Scratch_1.4_Download):
- Microsoft Windows - Regular Installation
Requires Windows 2000 or later.
Includes: Windows XP, Windows Vista, Windows 7
Install like normal. Double-click the downloaded file. Follow the instructions. The program should be installed quickly. Look for the cat, as that's usually what you want to double-click to run Scratch.
- Microsoft Windows – Special Installation- ZIP File (http://download.scratch.mit.edu/WinScratch1.4.zip)
If you don't have Administrator rights to install software on your computer (or your students' computers), then you can still run Scratch! - Download this ZIP file
- Once downloaded, right-click on the file, choose "Extract ..."
- Extract this to whatever folder you'll remember. (I recommend the Desktop.)
- To run Scratch, double-clicking the "Scratch.exe" file. (It will run slower than normal, but it will run!)
- If you are a teacher asking your class to download this (or handing it around on small USB drives) you may want to delete the "Samples" folder, as this removes over 30% of the size. Just Extract the file, remove the folders you don't want, and zip the folders again.
- Mac (OSX)
Requires Mac OSX 10.4 or later, including: 10.4 (Tiger), 10.5 (Leopard), 10.6 (Snow Leopard) and 10.7 (Lion)
- Double-click to unzip the dmg file. Follow the instructions and drag the Scratch file into your Applications. If you don't have Administrator rights, you can try double-clicking in the unzip/dmg/StuffIt window.
- If it works, it will probably run really slowly.
- Ubuntu Linux
Requires Ubuntu 9.04 or later, including: 9.04 (Jaunty Jackalope), 9.10 (Karmic Koala), 10.04 (Lucid Lynx), 11.04 (Natty Narwhal), 11.10 (Oneiric Ocelot)
- Installation instructions for Linux are here
If Scratch isn't running yet, then you can start it by double-clicking the kitty cat. When Scratch loads, it should look like this:
