- Download the correct 32/64bit version of Java 6u39 for your system. (jre-6u38-windows-x64.exe for 64bit Windows)
How do you know if you have a 32bit or 64bit Windows? Click START, Right click "Computer" select "Properties". It should be listed under system type. Direct Downloads from Oracle (no sign in needed): - Install on to your computer.
- Edit the mt.cfg file changing the JVM line. Make sure you're using the correct drive letter and file location for your install. These are the most common settings:
Note: With a new install mt.cfg doesn't exist until you run MapToolLauncher.exe. You can create a new file with that name with notepad or run MapToolLauncher, close MapTool then edit with notepad.
Code: Select all
MAXMEM=1024 MINMEM=64 STACKSIZE=3 JVM=C:\Program Files\Java\jre6\bin\javaw PROMPT=false
- Start MapTool with "MapToolLauncher.exe"
- Verify your java version in b87 through the Help menu and the "Gather Debug Information" option. The java version will be displayed under Java Information.
Update:
Apparently Java 7 version 10 has a bug where if used with MT it will not find the JAR file. You currently shouldn't be using Java 7, but if you get that error, this is why.
Update:
There is a related thread that discusses the one-click installation of java 6 with no extra configuration needed. Soon this will be moved to the HOWTO section with directions.

Update: (4/1/13)
Just noting the latest and last direct links for java 6. I have not tested this with MapTool yet, but I plan to make a 2 minute video showing a fresh install of MapTool. For browser operation, they recommend installing both 32bit and 64bit versions for 64bit systems.
