RuntimeException: Application "" could not be found in the registry.

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:

   eclipse.application=
   

3. Edit eclipse.ini.

   Contents of eclipse.ini:

   -startup
   plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
   --launcher.library

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

Answer 2

Your first eclipse included C/C++ as part of its zip, as it was Eclipse for C/C++ developers. That's what the product org.eclipse.epp.package.cpp.product says. You didn't install the C/C++ runtime separately, although you might have installed the source plugins separately. But however you told it to remove configurations wiped out that product, and now that install is broken. You're best bet is to remove it and unzip your ZIP again.

Other options: You can roll back your configuration change, using the p2 director on the command line. Something like:

eclipse/eclipse -noSplash \
-application org.eclipse.equinox.p2.director \
-repository file:$(pwd)/eclipse/p2/org.eclipse.equinox.p2.engine/profileRegistry/SDKProfile.profile \
-profile SDKProfile \
-revert 1299499722731

See http://pweclipse.blogspot.com/2011/03/working-state-from-p2-update.html for a description of the process (it's a hit or miss proposition, but maybe better than deleting and unzipping).

Answer 3

Control Panel-> Advanced System Setting -> Environment Variables ->

Now you have to do 2 things:

1-Create a new variable variable name=JAVA_HOME
variable value=C:\Program Files\Java\jdk1.7.0_01

2-Edite the Path variable and add this at the end of that
;%JAVA_HOME%\bin
