Capella not started


I’m trying to install Capella on PC of some of my Altran colleagues. But Capella does not start on their PC.

They have following message :
Generally, this message appears when Java version is not recent, but in our case we have version 1.8 of Java.

We’ve seen on the Capella/Installation guide ([][https_wiki.eclipse.org_Capella_Installation_Guide]) a correction that can be done on eclipse.ini file :

But we cannot see the corresponding lines on the eclipse.ini :

Do you have an idea to help us in solving this problem?

Hi Benoit,
First of all the error you get is due to a Java version problem. Either it is picking up another Java version than the 1.8 version if you have more than one version installed. If you have only java 1.8 installed, then it is because your java version is a 32 bits version and it should be a 64 bits version.

To check that, press the “Win button” + R, and then type “cmd”. It should open a command window.
In this command window, type “java -version”. It should display something like:
java version “1.8.0_121”
Java™ SE Runtime Environment (build 1.8.0_121-b09)
Java HotSpot™ 64-Bit Server VM (build 25.201-b09, mixed mode)

You should check 2 things: (1) the java version and (2) that it is a 64-bit version.

Now if you do have a java 1.8 64 bits version, then it is not picking this one and you can look at modifying the eclipse.ini file.
You can put the 2 -vm lines just before the -vmargs line

I hope this helps.


It was efffectively due to Java configuration in our computers.

Thanks for reactivity Stephane.
