  2. Click Change.
  3. In the setup dialog, select Repair.

Troubleshooting a Java-Related Error Message When Installing or Uninstalling the Plug-in

You might see the following error message when you attempt to install or uninstall the plug-in:

"Citrix Single sign-on has detected that one or more Java software programs or files are currently in use. Please close all programs and stop all Java-related services before continuing. "

Typically, this error occurs if you are installing the plug-in on a computer also running a Web server service such as Apache Tomcat or Apache HTTP server. Also, this error might be seen if you are installing the plug-in on a XenApp server with a License Management Console installed.

In this case, perform the following steps:
  1. Stop the service.
  2. Install or uninstall the plug-in.
  3. Restart the service.
