Question

Background

Goal: I am attempting to install the Simics Tools for Eclipse plugin on Windows 7 64-bit.

I am using Eclipse Indigo for Java (64-bit <– This will be a problem later) and have just installed the C/C++ IDE plugin, GEF draw2d plugin, and the Simics Tools for Eclipse. Once the installation of these plugins successfully finished, I restarted Eclipse and proceeded to launch Simics Control from inside Eclipse. An error dialog stated that this plugin could not run on 64 bit Eclipse.

To solve this problem, I decided to install a 32-bit version of Eclipse next to my current setup and to uninstall the plugins I had just installed (C/C++, GEF, and Simics) from Eclipse. First, I was going to remove the plugins to avoid wasting space. I went to Help->About->Installation Details and selected the installed plugins to uninstall. Removing the plugins appeared to be successful until I restarted Eclipse.

Issue

After the removal of the plugins, when Eclipse launches, the splash screen appears without a progress bar along the bottom to show what is currently being loaded. After a few seconds, the splash screen disappears and an error dialog shows up: An error has occurred. See the log file C:\Program Files (x86)\eclipse\configuration\1322503657546.log

The important line appears to be java.lang.RuntimeException: Application "" could not be found in the registry. After searching the web, it appears that this is a generic error.

Resources:

• Eclipse Forums
• I tried removing my
  /eclipse/configuration/ folder and relaunching, but that created a whole bunch of
  new errors.

Ideas

1. Removing /eclipse/configuration folder and relaunching. Failed.

2. Edit config.ini. Should I be concerned that eclipse.product and eclipse.application are blank?

   Contents of config.ini:

   #This configuration file was written by:
   org.eclipse.equinox.internal.frameworkadmin.equinox.EquinoxFwConfigFileParser
   #Mon Nov 28 11:18:26 CST 2011

   osgi.bundles.defaultStartLevel=4
   eclipse.p2.data.area=@config.dir/../p2/
   eclipse.application=
   

3. Edit eclipse.ini.

   Contents of eclipse.ini:

   -startup
   plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
   --launcher.library
   plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.100.v20110502
   -showsplash

   -vmargs
   -Dosgi.requiredJavaVersion=1.5
   -Xms512m
   -Xmx1024m
   

How can I successfully launch Eclipse again? I would really rather not have to perform a clean install since it took a long time to get it set up.

Thanks in advance!

Answer 1

Empty

eclipse.application= 

in config.ini is problem.
Default value you can use is

eclipse.application=org.eclipse.ui.ide.workbench

Same counts for empty eclipse.product

eclipse.product=org.eclipse.platform.ide
