Re-installed the system and opened MyEclipse found it's not open.

The error message is as follows:

The General meaning is:

Java JDK and JRE are the necessary environments for running MyEclipse,

Virtual machine not found in D:\ Balabala directory

Seeing this information, I thought my Java environment was not configured well, win+r cmd

Java Normal

Javac Normal

Degree Niang said your environment is not well-equipped!

Obviously it wasn't the problem, I had to figure it out myself.

Take a decisive look at the MyEclipse configuration file, which is your myeclipse. myeclipse.ini file in the installation directory

#utf8 (do not remove)-startupplugins/org.eclipse.equinox.launcher_1.3.0. v20130327-1440.jar--launcher.libraryplugins/org.eclipse.equinox.launcher.i18n.win32.win32.x86_64_3.2.0.

Dawned.. The system was messed up.

Then configure the path above to your installation directory. So easy
