Additional notes about installation on Windows with 64-bit Java

===============================================================

 

Many problems have been reported by Windows users attempting to run AstroImageJ with 32-bit Java. These problems are likely due to the very limited memory space available for running AIJ under 32-bit Java. Therefore, it is strongly recommended to run AIJ under a Windows 64-bit OS and 64-bit Java. To run AIJ with 64-bit Java use the x64 installation file mentioned above. If you prefer to install AIJ and use the system installed 64-bit Java runtime environment (jre), extra steps are required during installation since AIJ defaults to 32-bit Java, even if 64-bit Java has been installed on the computer.
