Understanding JSW Issues


Troubles Opening JSW Files

Ichitaro Disappeared

You attempt to load your JSW file and get an error such as "%%os%% Can't Open The JSW File Extension". Customarily, this means that Ichitaro is not installed on %%os%%. Your operating system cannot associate your JSW with Ichitaro, so double-clicking the file won't work.


Tip: If you know of another program that can open your JSW file, you can try opening it by selecting the application from the programs listed.


Incorrect Ichitaro Version

Sometimes your installed version of Ichitaro won't support your Ichitaro 4.0 Document file. Visit the JustSystems website to download (or purchase) the latest version of Ichitaro. Most of the time your Ichitaro 4.0 Document file was created by a newer Ichitaro than what you have installed.


Tip: Sometimes you can get a clue about the version of JSW file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Summary: Not having the right Ichitaro version on your computer can cause problems opening JSW files.


Other Causes of JSW File Opening Problems

Assuming you have the right Ichitaro version installed, other problems can prevent you from opening JSW files. If you're still experiencing problems opening JSW files, there could be other computer problems. Problems unrelated to software:

  • File references in the Windows Registry for JSW are wrong
  • Deletion of the JSW file description from the Registry by mistake
  • Defective install of a JSW program, such as Ichitaro
  • File corruption affecting your JSW file
  • The JSW is infected with a virus
  • Drivers associated with JSW software need to be updated
