JDeveloper 11g Not Opening

I am trying to open up jdeveloper 11g and it is doing nothing. I am getting the following error when I run jdev.exe

IDE boot startup failed.

I attempted to install oracle servicce bus and oracle database express edition, is it possible that some file was overwritten?

In my case, I need update JDevepoper to newest. It will fix this issue

Another option is setting proxy for Jdeveloper. Choose Window/Preference, search proxy, choose Proxy Setting. Enter proxy information.

Next thing to do after deleting the system11.1.x.x.x.x folder is to remove or uninstall the whole JDev and after that install it again. Then all files which might be overwritten by the other installations should be back in their original version.

You should install JDev into a path without spaces in.

Try removing JDeveloper's system directory Should be under C:\Users\yourUser\AppData\Roaming\JDeveloper and then restarting JDeveloper

Looks like it is trying to open a file that it has no access to over the network.
