Download the Free Trial Version of
CoStat 6.3 for Windows

Installation Notes:

• Technical Support Is Free before and after you buy a license. If you can't figure something out or don't like something, please don't give up. Contact technical support. Maybe we can help.
• Slightly Crippled - Unless you buy a license and use Help : Register to register this program, this trial version of CoStat will cover up one line of data on the screen with "CoStat (not registered)" and will suppress printing crucial statistics (it prints "not registered" instead). The line of data in the spreadsheet covered up by the red letters is still accessible (move the cursor to one of the cells and look in the data entry field above the spreadsheet). Otherwise, this is the complete version of CoStat. We are sorry about the crippling. We felt we had to do something to encourage people to buy a license and not just use the free trial versions forever. CoHort Software is a small company of people trying to make a living writing, selling, and supporting this software. We don't have other jobs or government grants. We can't afford to just give CoStat away. If you like CoStat, please buy a license.
• Uninstaller - The installer includes an uninstaller. So, in the unlikely event that you some day wish to uninstall CoStat, that would be easy to do.

Install CoStat:

1. Windows users: if an older version of CoStat 6.x is already installed on your computer, uninstall it.
   1. Use Start : Settings (on older computers) : Control Panel : Add/Remove Programs.
   2. Uninstall CoHort, CoPlot, and/or CoStat if they are listed.
2. Download and install the latest version of CoStat, which includes Java(?).
   1. Click on costat6311Win.exe (15,879,025 bytes) and choose to Run it.
      (Estimated download time for a 56K modem: 50 minutes.)

Common Download Problems

• If your browser changes the file's name before saving it, change the name back to the name specified above.
• If the download freezes at 99% for more than a minute, try cancelling it and starting the download again. Usually, it will go super fast the second time and get to 100%. If that doesn't work, try downloading with a different browser (if you have one) or on a different computer. If that doesn't work, please send an email to info@cohort.com.

More Installation Notes

1. File Associations - The installer associates .dt files with CoStat. Thus, you can click on a .dt file listed in Windows Explorer (also called "My Computer") to launch CoStat and view that file.
2. Java - The installer includes a copy of the Java Runtime Environment and installs it in the c:\Program Files\CoHort\cohort6\jre directory, where it will be used by CoHort programs and not by other programs. Thus, it doesn't matter if there is a version of Java already installed on your computer before you run this installer. Also, the CoHort programs won't be affected if you install another version of Java via a standard Java installer from Sun, because the CoHort programs will continue to use their local copy of Java.
3. Run From Command Line - Although few people will need to do this, the CoHort programs can be run from the command line. The .bat files to do this are included in this installation.
4. Installing On A Network File Server - We no longer recommend that you use a network file server to store the CoHort programs. It leads to excessive network traffic and makes the program's start up time much longer.

Common Problems Running CoStat

When you exit CoStat, you get a warning like "Warning: Default charset MS932 not supported; using ISO-8859-1 instead."

This problem can occur on some computers where the default language is not English. The solution is:

1. Right-click (Apple users: use shift-click) on charsets.jar
2. Choose Save Target As (or "Save link as" on some browsers).
3. In the file dialog that pops up:
   • Set Save As Type to be All Files.
   • Make sure the file gets saved with the name charsets.jar. If your browser changed the file name (for example, to charsets.zip), change the name back to charsets.jar.
   • Choose to save the file in your cohort6 directory in the sub-directory called "jre/lib/"
     (on Windows, this is often c:\Program Files\cohort6\jre\lib;
     on Mac OS X, this is often (Macintosh HD)/Applications/CoHort/cohort6/jre/lib;
     on Linux and UNIX, this is often /usr/local/bin/cohort6/jre/lib).
4. If the file gets upzipped, something went wrong. Try to follow the steps above again, but with slight changes so that the file gets saved as one file.

The next time you run CoStat, the file will be detected by Java and the problem should go away.
