I really need to re-install it since I can't open it all of a sudden. How do I do this without deleting any work that I've done? The problem is that eclipse "failed to lodd JNI shard library" etc etc.

    Eclipse should leave your working directory(ies) alone. – Cᴏʀʏ Jul 23 '14 at 23:02
  • When I use Eclipse, all my work is in the workspace folder I've set up, plus other folders where I keep project sources and data separately. I'd definitely make a backup copy of the workspace. – ajb Jul 23 '14 at 23:03
  • You might save yourself a lot of time by reviewing the answers to the possible duplicate I linked before you go through the reinstallation process. – Cᴏʀʏ Jul 23 '14 at 23:05
  • I actually think the problem is that I have a 32-bit, since I wanted to try something out I installed a 64-bit JRE recently, so should I just delete my eclipse file and then install it again as 64-bit without any harm being done? Thanks for you help! – Joseph Jul 23 '14 at 23:08
  • Sound like a good opportunity to learn version control. – Thorbjørn Ravn Andersen Jul 24 '14 at 00:46
  • If you are using Eclipse 32-bit and JDK 64-bit; Eclipse won't work. Both must be of the same architecture (either 32-bit or 64-bit). – Mohamed El-Beltagy Jul 24 '14 at 01:42
  • In regards to your worries about your work; Eclipse keeps all projects as workspace(s). If you decided to change Eclipse to 64-bit, just make sure to open the same workspace again. – Mohamed El-Beltagy Jul 24 '14 at 01:44

Did you update your JRE/JDK recently? Check that you have JAVA_HOME points to a working Java installation. You might need to reinstall your Java, or even point your Eclipse to new JDK by modifying eclipse.ini file. Reinstalling Eclipse will probably accomplish nothing. Other than that, as long as you don't delete your workspace directory, your work should be safe.
