Well, you do have a reason. "Could not reserve enough space for object heap."
Take a look at the JVM parameters - specifcally -Xms and -Xmx

This is a feature of windows. It is part of a US military experiment
in "torture light".

For those sorts of things:

0. reboot.

1. if that does not work, uninstall anything you recently installed.

2. if that does not work, do an UPDATE reinstall of Windows

3. if that does not work, do a CLEAN reinstall of Windows and
reinstall all your software from scratch.
