Hello evryone
After downloading capella for trial, i extracted it and launched it. After getting asked for workspace I got the following message:
An error has occurred. See the log file

I am working on windows 10 (64 bits)
Capella 1.4.0
I tried modifying the ini file with
C:\Program Files (x86)\AdoptOpenJDK\jre-\bin\java.exe
But it didn’t change anything. Any idea where is th eproblem from?
Thank you for your help.


Hi Jean-Gui,
Yes, you have Java 11 installed on your machine and Capella is picking up (you can see it here: java.version=11.0.7)
You can try a few things:

  • uninstall Java 11
  • make sure that when you modify the eclipse.ici file, you place the -vm … argument before the -vmargs one
    I hope this helps

Hello Stéphane
Thank you for your answer. Uninstalling Java11 was the right call. About the -vm and -showsplash arguments it returned me an error code1 so I removed both, try with original .ini file and it was good. Problem solved.
Thank you
