GEN Studio does not start


Article ID: 243218


Updated On:


Gen - Workstation Toolset


When trying to open GEN Studio, it does not launch and produces a '.log' file within '%USERPROFILE%\AppData\Local\CA\Gen 8.6\cfg\GenStudio\workspace\.metadata'

The .log file contains java error references to the Gen Studio plugin files located in 'C:\Program Files (x86)\CA\gen86\Gen\GenStudio\plugins'

An example where the plugin '' could not be resolved: 

ENTRY 4 0 
!MESSAGE FrameworkEvent ERROR
org.osgi.framework.BundleException: Could not resolve module: [10]
Another singleton bundle selected: osgi.identity; osgi.identity=""; type="osgi.bundle"; version:Version=""; 


One potential cause is that Gen Studio was installed both product/PTFs on one machine and the changes were deploying to another machine, this may result in multiple versions of the plugins on the deployed machine.   


Release: 8.6

Component: Eclipse Gen Studio



The problem is related to Gen Studio plugin versioning issues.

Verify whether there are duplicate and/or older versions of the plugins in the Gen studio plugin folder 'C:\Program Files (x86)\CA\gen86\Gen\GenStudio\plugins'.    Remove the duplicate/older versions of plugin may resolve the issue.

Also, before starting Gen Studio, remove the directories of '/Workspace' and '/Configuration' from within ''%USERPROFILE%\AppData\Local\CA\Gen 8.6\cfg\GenStudio' to clear out old plugin references.
