After opening Eclipse once and without updating, it does not open again. It spits out the error "The Eclipse executable launcher was unable to locate its companion shared library." and does not open. I have Windows and used 7-Zip to unzip the file (I have read that windows default unzip tool corrupts the file). I would like to emphasize that it works once and without updating, but then if closed, will not open again. Thanks for any answers.

That's a very weird behavior.

The The Eclipse executable launcher was unable to locate its companion shared library error popup does indeed happen when you don't expand the archive according to Windows' bizarre requirements, and it seems you've documented yourself well enough before posting this.

I would advise:

  • erasing the eclipse folder
  • copying the downloaded archive to a "safe" folder like "My Documents"
  • right-clicking the archive there, and "extract here"
  • moving the extracted folder back to its location (32-bit or 64-bit Program Files)
  • trying to launch again

  • It worked fine until I dragged the eclipse application part to the desktop. Would that cause a problem? – The Boss Aug 08 '13 at 18:06
  • @user2665414 Not sure I understand. Did you drag the folder to the desktop or just the binary? – Mena Aug 08 '13 at 18:18
  • It's the actual application part (It's a bad description I know). When the folder is open with the Eclipse sign? I'm going to try just running from documents though. And that worked. I just can't copy it to my desktop. But still solve the problem, thanks! – The Boss Aug 08 '13 at 18:29

    Don't drag just the Eclipse executable to the desktop, create a link (shortcut) if you want a copy on the desktop. Eclipse's executable launcher must live in the directory containing all of Eclipse. – Jim Garrison Aug 08 '13 at 18:40
  • @JimGarrison aah now I understand what OP meant. +1 for your comment, totally agree, the binary must be in its own folder. – Mena Aug 08 '13 at 18:46
