[Dataexplorer-help] DataExplorer doesn´t start (OS X 10.11.6)

[Daniel Heise]

I try to run DataExplorer on my MacBook pro with OS X 10.11.6, but until 
now without success.

First I installed Java, and the Terminal prompts the following:

java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-468-11M4833)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-468, mixed mode)

Java therefore seems not to be the problem.

Then I downloaded the file DataExplorer-3.2.9_Mac_64.dmg and executed it.
After that, DataExplorer.app correctly occurred in the Applications folder.
However, when I click on DataExplorer.app, the "icon" appears in the 
dock, but disappears after about 1 second, so I can´t keep the program 
running.

To get  some more information I took the advice from the 
nongnu.org-website and entered "java -Dfile.encoding=UTF-8 -jar 
./DataExplorer.jar" into the Terminal (after changing the directory to 
Applications). This is the answer:

Daniels-MacBook-Pro:Applications daniel$ java -Dfile.encoding=UTF-8 -jar 
./DataExplorer.jar
Unable to access jarfile ./DataExplorer.jar
Daniels-MacBook-Pro:Applications daniel$


Any idea what I´ve done wrong?

Thanks in advance,

Daniel
