"java.lang.runtimeexception: application “org.eclipse.ui.ide.workbench” could not be found in the registry" Code Answer

ok thanks everyone i found the solution, which was the following:

control panel → view advanced system settings → advanced tab → environment variables
now you have to do 2 things:
1. create a new variable (click the new button):
  - variable name: java_home
  - variable value: c:program filesjava[your java version]
2. edit the path variable and add this to the end of that:
```
;%java_home%bin
```
