MapManInst-3.5.1R2 install error - java virtual machine

Hi Readers,

Over the past week I've installed and uninstalled v3.5.1R2 several times.
I've even had it working, only to come back later and find it not working anymore.
I gather it's a problem with the Java association - perhaps my computer keeps updating Java to a version that MapMan doesn't like?

I'm speculating, I don't pretend to know much of what goes on inside the box.

I'd be very grateful for any advice.

Cheers, Mick

Dear Mick

I am sorry to hear that, can you give some bacjground regarding what happens and your operating system?
e.g. does MapMan start and terminate or not start at all and do you get any error message?

Also try on a comand line (Windoes search for CMD)
java -version

and report what it says if java is properly recoginzed it should give you the version.

Best Wishes
Björn

Open the Control Panel
Go to System
Go to Advanced Systems Properties
Then Environment Variables
In System Variables, click Add
New Variable Name: _JAVA_OPTIONS
New Variable Value: -Xmx512M
Click OK

That's it, your Java program should now be able to execute properly.
For those interested, Java -Xmx/s is the configuration parameter that control the amount of memory Java uses.

Xmx sets the maximum heap memory size
Xms sets the minimum heap memory size
