install4j After installation application doesn't run

Question

I have following problem with my install4j installer. My app. doesn't start when I run it from installer.

I see in installer logs that runScript with ID=260 completed successfully:

[INFO] com.install4j.runtime.beans.actions.misc.RunExecutableAction [ID 260]: Execute action

In error.log i found only standard error that doesn't influence to app. workability:

P.S. For Windows installer following case works correct.

Answer 1

If your "Request privileges" action has its "Linux privilege requirement" property set to "Try to obtain privileges" and the "Run executable or batch file" action has its "Action elevation type" property set to "Elevate to maximum available privileges", the application will be started as root and may not have access to your display.

Set the "Action elevation type" property to "Do not elevate" to fix this problem.
