"Companion shared library"? [message #1425041]

I tried to install Eclipse because it was recommended to me. I tried two different packages but when I click on eclipse.exe or eclipsec.exe, I get the message

The Eclipse executable launcher was unable to locate its companion shared library.

I'm a newbie to this platform so I assumed that any package I downloaded would have all of the associated files that I would need. I looked at other posts but I don't see this problem mentioned but I get this same message again and again.

Any ideas or suggestions? Thanks.

Which file did you download? What OS are you on? Where did you unzip it? With what tool did you unzip it?

Make sure you actually own or have read permissions on everything you've unzipped. Beyond that, give us concrete details to work from.

Missing Java?

I guess that you're using some flavor of Windows.

Please open Console and type:

java -version

and post what the response is.

Please read the Eclipse installation instructions at
<https://wiki.eclipse.org/Eclipse/Installation>.

I'm having that same problem with "The eclipse executable launcher was unable to locate its companion shared library." When I type java -version in Command Prompt, I get the following message:
Error: could not open 'C:\Program Files\Java\jre7\lib\amd64\jvm.cfg'

Does this help in answering the question of how to fix this error?

Did you read (and follow) the instructions in the Announcement at the top of this forum, titled "Eclipse won't start? READ THIS FIRST"?

Sounds like you may have a 64 bit 'java' installed on a 32 bit bit
machine? 
Or else your "PATH" is set wrong? 
Once you know what "bitness" your machine is, you can double check
your Java and Eclipse: 
 
32 bit machine: requires 32 bit Java and 32 bit Eclipse. 
 
64 bit machine: can use either 32 or 64 bit Java and Eclipse, but
which ever you pick, 
they must "match" each other (both be 32 bit, or both be 64 bit). 
 
This "bitness mis-match" is the most common problem leading to "can
not find companion shared library", 
in my experience.
