Hello there,
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.

Check your Citrix license server to be sure that valid licenses exist. Do you have per user licensing? If so, it's possible that the user license isn't functioning correctly.

User access the Citrix published app in windows 7 x 64 bit PC via Citrix Web interface using normal user account,when user clicks on the Published app to launch, Protocol driver error pops-up.
But the same user has no issue, launching published app, if PC logged in as administrator.
This is strange but true, I validated it myself. Not sure what is happening here?
Please advise.
