HTTP Store requires additional configuration before being added to the Citrix Receiver. Please contact your system administrator. This is because the best practice is to always use SSL, whether on the front end for clients or backend communication to your servers. I always take this approach in Production environments. In the Control Panel, open Internet Options and select the Connections tab. In Server Manager, navigate to Local Server again, and click the “On” link next to IE Enhanced Security Configuration: Change both settings to Off and click OK to save these settings: Install Citrix Delivery Controller Role. Next, we’ll go ahead and install the Citrix Delivery Controller role on the server, using the process described below. Hi everyone, I have an issue on Windows 10 attempting to connect to our Citrix Xenapp server over the internet. I have tested Citrix Receiver 4.12 and the new Citrix Workspace and both experience the same issue. Basically when trying to initially configure an account in the client, I experience t. (This is the only option available because server groups are not available in nondomain-joined servers.) Important: In multiple server deployments, use only one server at a time to make changes to the configuration of the server group. Ensure that the Citrix StoreFront management console is not running on any of the other servers in the deployment.
Protocol Driver Error/Error 1046 is an issue related to the client (Receiver) not being able to create a connection to the server after an application is launched. Messages such as “Your version of Citrix Receiver does not support selected encryption” are generated when this issue occurs.
There are various reasons that Protocol Driver Error/Error 1046 could be generated, ranging from the client through to the Citrix hosting infrastructure. Below are several troubleshooting recommendations on what to try to resolve quickly.
How to ResolveProtocol Driver Error/Error 1046
The first thing to do when you get a Protocol Driver Error/Error 1046 is to verify Citrix Receiver/Workspace is upgraded to the latest version if possible or the latest version that has been validated in the destination environment.
If upgrading receiver doesn’t help, or if the latest version is already running on the affected workstation, next recommendation would be to perform a full uninstall of receiver utilizing the Citrix Receiver Cleanup Utility available at the following link:https://support.citrix.com/article/CTX137494 . Once receiver is fully uninstalled, reboot the workstation and then reinstall the appropriate version of Citrix Receiver/Workspace.
Note, if version 1909 or later of Citrix Workspace is being utilized, the installer can perform the appropriate cleanup steps so that the Citrix Receiver Cleanup Utility is no longer needed. Instead, utilize the/forceinstallcommand line switch when running the Workspace installer:CitrixWorkspaceApp.exe /forceinstall.
If the/forceinstallswitch doesn’t fix the Protocol Driver Error/Error 1046 issue, the Cleanup Utility may still be something to try as even with versions 1909 and greater of Workspace there may be remnants of older/corrupt installations that may affect performance.
If the workstation is still exhibiting the issue, next verify that the following Registry key is set to True:
Unable To Launch Citrix Receiver
- Key location: HKLMSOFTWAREWow6432NodePoliciesCitrixICA ClientEngineLockdown ProfilesAll RegionsLockdownLogonLocal Credentials
- String Name (REG_SZ): LegacyLocalUserNameAndPassword
- Data: True
If the problem persists, try increasing the following timeout values in the registry:
- Key location: HKEY_LOCAL_MACHINESOFTWAREWow6432nodeCitrixICA Client
- Value Name (REG_DWORD): VdLoadUnLoadTimeOut
- Data (in Decimal): 5
The default for VdLoadUnLoadTimeOut is 1 second, this increases it to 5 seconds. Attempt reconnection. If the problem persists, try increasing this value to 10, 15, and 20 to see if the issue continues.
Note, the above registry locations are valid for 64-bit versions of Windows. For more information or for the Registry values for 32-bit versions of Windows, check Citrix’s article at https://support.citrix.com/article/CTX133536.
