The official GIMP website does not provide installation media for Windows, but you can download the install files from
http://sourceforge.net/projects/gimp-win/files. The current version is 2.8.0
1. Locate where you saved the install file on your system and open it to start the installation.
2. Select your language to use.
3. Click the Install button for the program to use the default options or click the Customize button to choose a number of specific ones.
a) If you choose Customize, you will first see the GNU license option. Click NEXT to accept it.
b) Now you can choose where to write the program files. Browse for a location or choose NEXT to accept the default.
Then you can do either a:
– Full installation, which installs all the components, including Python and PostScript scripting support. Or
– Compact or Custom installation that allows you to choose any or all of the components.
c) Once you have done that, you can select file associations. This will allow you to open specific file types automatically by double clicking on the files. There is a wide range of files here, but only the native GIMP files are selected. You can choose others, like Adobe Photoshop, Corel PaintshopPro and many others. Click NEXT to continue.
d) Now you can create a desktop icon and/or a quick launch icon (one that resides in the Quick Launch toolbar).
e) Finally, you’ll see a summary of all of your choices. Click the Install button to begin the install.
4. The installation will start, and files will be copied to your PC.
5. Once it completes, you’ll see the Completing the GIMP Setup window. Click the FINISH button to exit.
