> Windows Installation Download and expand the self-extracting ZIP archive to the C: drive. To run ImageJ, open the ImageJ folder and double-click on the "ImageJ" shortcut (a microscope with an errow point at it). This shortcut assumes the ImageJ folder is at C:\ImageJ. If this is not the case, right-click on the shortcut and edit the "Target:" and "Start in" fields of the "Shortcut" properties to reflect the new location. Creating a Desktop Icon To create an ImageJ desktop icon, open the ImageJ folder, right-click on the ImageJ shortcut, drag it to the desktop, release the right mouse button, and select "Create Shortcut Here" from the popup menu. Requirements ImageJ will run on a machine with 64MB but it runs better with 256MB or more, particularly when working with large images and/or stacks. Memory To increase the amount of memory available to ImageJ, edit the -mx option in the "Target:" field of the of the "Shortcut" properties of the ImageJ shortcut. The default is 80MB. For example, to increase the available memory from 80MB to 340MB, change the "Target" line from
>     C:\ImageJ\jre\bin\jrew.exe -mx80m -cp ij.jar;tools11.jar ij.ImageJ
> to
>     C:\ImageJ\jre\bin\jrew.exe -mx340m -cp ij.jar;tools11.jar ij.ImageJ
To avoid virtual memory "thrashing" set the -mx option to no more than 2/3 real RAM. Upgrading To upgrade to the latest version of ImageJ, replace the ij.jar file in the ImageJ folder with a newer one from http://rsb.info.nih.gov/ij/upgrade/. After upgrading, the commands in the File menu that use QuickTime for Java will be gone but you can still run these plugins directly from the Plugins/QuickTime submenu.
