Camtasia (Windows): The application was unable to start correctly (oxc0000005)


This error can appear if Symantec Endpoint Protection 12 and Citrix Office Plugins are both installed on the system.  


  • The best workaround is to uninstall the Citrix Office Plugins from the control panel.  Camtasia Studio should then launch successfully.
  • Another user reported that turning off "application and device control" under Proactive Threat Protection and disabling "Network Intrusion Protection" within SEP 12 resolved the issue.
  • Users have also reported that uninstalling IOBit Advanced System Care Free version 11 resolved the issue
