Open the following file with using the Memo Pad (without starting the e² studio).
<Installation folder of the e² studio>\eclipse\e2studio.ini
Then replace "-Xmx1024m" by other settings such as "-Xmx768m" and "-Xmx512m."
The above setting -Xmx specifies a virtual memory capacity in the Java execution environment. However, in some PC environment a desired capacity may not be secured as specified. This causes a startup failure of a Java virtual machine and the problem in this question.
As changing the set value to smaller, you will be able to start the e² studio. However, if it is set too small, performance may be decreased, or some of the plug-ins may not operate. To avoid this, adjust the setting within the range of 512 to 1024.
