Installation of Citrix extension leads to error "Could Not Read Citrix Registry Key: 'SOFTWARE\Citrix\Install\ICA Client' value: 'InstallFolder'"

What has to be done when attempting to install the Citrix extension from Studio, following error message is obtained - "Could Not Read Citrix Registry Key: 'SOFTWARE\Citrix\Install\ICA Client' value: 'InstallFolder'"?

The most common cause of this " Could Not Read Citrix Registry Key" issue obtained when installation of the Citrix extension from Studio, is due to a Citrix receiver or an incompatible version of the same being present .

Only the Citrix Receiver or Workspace clients are supported with the Citrix extension and when attempting to install the Citrix extension, it will attempt to validate the registry keys associated with the same. In the absence of this registry key, the above error would be encountered. A simple example would be if a machine has Citrix Receiver for Universal Windows Platform version installed, which is not supported. If the Receiver or Workspace client is not installed, the same will have to be installed.

If the Citrix receiver or workspace was recently installed prior to attempting to install the Citrix extension and the error appears, a system restart is recommended and then attempt to enable the Citrix extension.

An additional trouble shooting that can be done if the error still persists, is to perform the installation of the Citrix extension from a Command prompt launched in administrator mode. (More details here  ).
