Download Systems.zip.

 
 To Install Systems
 

To install Systems of ODEs, unzip systems.zip, and copy the files

systems.exe (the application, Systems)
systems.chm (the Compiled HTML Help file, systems)
spb.dll (an add-on library)
webpage.ini
All files with the extensions SYW or ENV
into the directory of your choice.

No formal installation process is necessary. Systems of ODEs does not make any changes to your operating system and uninstalls cleanly.

 
 To Run Systems
 

To run Systems, move to the directory containing the files and select the application Systems, that is, Systems.exe. Windows must first be updated by installing Microsoft .NET Framework 1.1.

If you find any bugs, please cut and paste the error message, describe what you were doing at the time, and email this information to me: David Lovelock at dsl@math.arizona.edu. Thank you.

 
 To Upgrade Systems
 

To upgrade Systems, just overwrite the old Systems.exe and Systems.chm with the upgraded Systems.exe and Systems.chm.

 
 To Uninstall Systems
 

To uninstall Systems of ODEs, delete the files

systems.exe (the application, Systems)
systems.chm (the Compiled HTML Help file, systems)
spb.dll (the add-on library).
