I\'m having trouble with the SaveGIF function in library (animation). The function gives me this error:

Answer 1

You probably did not edit your PATH variable. On Windows 7 (but will probably work on earlier versions to) go to:

start menu

Right click computer -> properties

Advanced System Settings

Environment Variables

Then under "System variables" (the lower pane) find the variable "path", select it and click edit.

You are interested in the content of Variable value (maybe copy it to a text editor to read it better). It should contain the link to imagemagick in it, seperated by semicolons from other variables. For me the path to imagemagick is:

C:\Program Files\ImageMagick-6.6.7-Q16

Make sure you only add it, not change anything else to the path variable. Add it with a semicolon.
