JMRI Install Guide: 64-bit Windows
This page is a start at documenting how to use JMRI on 64-bit Windows.JMRI runs in 32 bit mode, even on 64-bit Windows systems.
Even after installing Java on a Windows Vista 64-bit computer, JMRI applications won't start because the "java" command can't be found.
John Sacrey provided instructions on how to update the Windows "path" variable so that Java is found:
-
This will get you to where the System Environment variables are defined:
- Right Click on "My Computer" and select "Properties"
- Click the "Advanced" tab
- Click the "Environment Variables" button
- Scroll the System variables list until you see "Path", select it
- Click the "Edit" button and it will bring up an edit box
- Locate "%SystemRoot%\system32;" in the string and insert "%systemroot%\SysWOW64;" after it, minus the quotation marks.
This works on BOTH XP x64 and Vista x64.
