Error number 2313: "The ICA Client received a corrupt ICA File. ICA File section WFClient contains duplicate keys named ()"

When Logging into web interface with ICA Client 10 or newer you get the following message

"Error number 2313: "The ICA Client received a corrupt ICA File. ICA File section WFClient contains duplicate keys named ()"

ICA client 10 and newer performs ICA file validation. If any errors (eg. Duplicate) entries are found the client refuses to run the ICA file. This validation did not occur in older ICA Client versions, so you may only see the problem when you upgrade your ICA clients in an environment that makes use of ICA files.

Alos Check Launch.ica and Template.ica file on Web Interface or Nfuse servers for entries that are being duplicated. If they are present in these file remove them. You may also need to delete the users appsrv.ini file which may now contain the duplicate entries.
