I've tried uninstalling and reinstalling FB3, even uninstalling VS2010 and related tools but no luck. It just started happening And I can't figure out why. I've even tried blowing away my workspace and getting a fresh build from teamprise. The app I'm attempting to debug works fine on everyone else's machines. Any ideas short of a clean OS install? !ENTRY org.eclipse.core.jobs 4 2 2010-06-14 16:38:47.780 !MESSAGE An internal error occurred during: "Launching VisionLink". !STACK 0 java.lang.NullPointerException at com.adobe.flexbuilder.project.dotnet.DotNetServerManager.startInstance(Unknown Source) at com.adobe.flexbuilder.debug.launching.AbstractFlexLaunchDelegate.preLaunchCheck(AbstractFlexLaunchDelegate.java:432) at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:717) at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:608) at org.eclipse.debug.internal.ui.DebugUIPlugin.buildAndLaunch(DebugUIPlugin.java:899) at org.eclipse.debug.internal.ui.DebugUIPlugin$7.run(DebugUIPlugin.java:1102) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
I just had my IT dept wipe my laptop clean with a brand new OS install and I STILL get this error after installing Flex Builder 3 from scratch.
I encounter the same problem, need help.
