I installed EAP a tried to run it by clicking a desktop icon. I started the server but then it ends up with this error.

Problem is probably in script, which starts server (run.bat). This script probably can not process correctly PATH variable, when this variable contains directories with spaces. When Java is installed in directory containing space (Program Files) and this directory path is on PATH, the server ends up with error. But this error may be generated by any directory with spaces in name when such directory is added to PATH variable.
