Installing JSim under Microsoft Windows

JSim's Windows distribution runs on Windows XP and Windows 7. JSim is not tested on Windows Vista but has run successfully on it in the past.

1. Download the appropriate JSim zip archive. Providing the following information will help us demonstrate JSim's continued utility to the funding agencies upon which we rely. Filling out this form will not result in your addition to any mailing lists. However, if you wish to be added to the JSim mailing list, please contact us.

   • Note: Internet Explorer(IE) users have sometimes noted that JSim download hang for several minutes at 99% complete. This appears to be a bug in IE. Our experience is that, if the user is patient, the download completes successfully after about five minutes.
2. Unpack the .zip file using your system's ZIP utility in a folder of your choice.
   • Note: You may need administrator privledges to install JSim into certain system directories such as 'Program Files'
3. Inside your installation folder, you will find a sub-folder win32\bin containing the following executable files:
   • jsim.bat : the JSim GUI application;
   • jsbatch.bat : the JSim text-based batch application.
   • jsfim.bat : the JSim functional imaging application.
   • jsserver.bat : the JSim remote server application.
   • jsreg.bat : adds JSim settings to the Windows registry
   • reg.exe : general purpose Windows registry tool used by jsreg.bat

   You may wish to make a short-cut to jsim.bat on your Desktop, or other convenient location. Other executables are useful only from the Windows command prompt.

4. The optional jsreg utility sets your Windows registry so that certain JSim files (e.g. .proj) are loaded into JSim when double-clicked. See here for more information.
5. Most users do not require the command-line utilities jsbatch.bat and jsfim.bat, which require some additional setup. If you do, do as follows (familiarity with .bat files and the DOS command line is assumed): Modify the PATH environment variable to include the directory containing jsim.bat and jsbatch.bat. Also, modify the JSIMHOME definition in jsbatch.bat or jsfim.bat to the the device:directory you have chosen for your JSim installation.
6. Optional advanced administration:
   • Customizing a JSim Installation : describes customization options, appropriate for advanced installation.
   • Administering a JSim Server : how to set up a network-accessible JSim computation server.
   • Administering a JSim-enabled Web Site : how to write web pages incorporating live JSim applets.

Using jsreg.bat

jsreg.bat adds settings to the Windows Registry that allows you to open .proj, .tac and .jsml files within JSim by double-clicking on their icons in Windows Explorer. These settings can cause problems for other programs in your system if they expect to open files with those same extensions. Conversely, the opening of files with those extensions within JSim can be impaired by other programs.

• Windows 7 - jsreg.bat must be run with administrator privledges. To do this either right mouse-click jsreg.bat and pick 'Run as adminstrator' or run cmd.exe as administrator and execute jsreg.bat at the command line.
• After running jsreg.bat you must reboot your computer to refresh the icon file associations.
• JSim .mod (models) extension conflicts with MS Windows use of .mod for media files. Double-clicking a JSim .mod file will not open up JSim by default. You must chose it explicitly.

This regrettable situation is unavoidable given the design of Windows, and is made worse by Microsoft refusing to give information to developers (outside of Redmond) as to how exactly the registry works. Therefore, you may need to muck with your registry a bit manually to get things just right. jsreg.bat is written so you can examine what is being done, and modify it if you are so inclined. If you relocate JSim on your system, rerunning jsreg.bat will repoint the registry appropriately.
