To run the Java ES installer, you need 500 Mbyte of disk space in the Windows system drive and 1.5 Gbyte in the destination drive.
The installer runs a check to determine whether your host has sufficient memory and disk space for the components you selected.
If the memory found on the host does not satisfy the Java ES recommendations, the installer displays a warning but allows the installation to proceed.
If the disk space found on the host is insufficient, the installer cannot proceed. You must resolve this problem before you resume the installation.
You can solve this problem by mapping the %TEMP% to any other drive that contains required amount of free space.
