How to ResolveProtocol Driver Error/Error 1046

Recommendation#2:

Time for another article, this time on the Native Receiver issue which gave me a lot of pain, was resolved by tweaking a simple setting. We had users reporting issues connecting to the Storefront store using native Receiver. The Receiver version was 4.1 running on Windows 8.1. The issue was random and a lot of. I am running both StoreFront 2.0 and Web Interface 5.4. To connect to the WI site, I need to enter in the full path to the config.xml file. However, when I enter just the I am able to choose between the stores I have configured for remote access in my StoreFront server. Citrix is working with Microsoft to address this Microsoft limitation. The supported workaround is to install Windows Server 2016 VDAs, which do not have Web Authentication Manager component that is misbehaving. LCM-7637 Data masking does not mask the license server if the configuration uses a dedicated license server.

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.

Recommendation #3:

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:

  • Key location: HKLMSOFTWAREWow6432NodePoliciesCitrixICA ClientEngineLockdown ProfilesAll RegionsLockdownLogonLocal Credentials
  • String Name (REG_SZ): LegacyLocalUserNameAndPassword
  • Data: True

Test again.

Recommendation #4:

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.
