When user logs in to Citrix web Interface, using his logon credentials, could log on, but when user to launch the App, following error pops up (attached screenshot):
"Unable to launch your application. Contact your help desk with the following information:Cannot connect to the Citrix XenApp server. Protocol Driver error.
However if I login as administrator on the same PC, I can login successfully and launch app and receive No Error.
Thanks and Regards
