Release History

19.05May 2019General Availability

Resolved Issues

Printer Plugin installation will report errors if it fails to install | 80118

Printer Plugin will suggest required KB is installed if it detects an installation failure

Known Issues

Performance monitor errors | 81269

Errors may occur when opening performance monitor and adding performance counters.


Use the following Windows command to correct issues with the performance monitor:

lodctr.exe / R

Wacom tablet cannot be mapped to non-primary display on Windows 7 and Server 2008 | 79144

This issue only affects Windows 7 and Windows Server 2008 SA.

After setting the Zero Client's tablet OSD setting to map to the non-primary display, pressing the Display Toggle function button on the tablet within PCoIP session does not map the Wacom tablet correctly to the monitors.

The issue can be seen in both local termination and bridged modes.


If monitor mapping is required for the Wacom tablet, only map the tablet to the primary display in the Zero Client's tablet OSD and in the Wacom properties.

Cintiq 22HD does not show in properties dialog for Windows | 76999

When using PCoIP Cloud Access Software for Windows Agents with a Zero Client locally terminating the Cintiq 22HD, the Wacom properties dialog reports that there is no tablet connected.  This prevents customization of the Wacom tablet on the Windows OS.  Default configuration does allow stylus pressure events to be processed, allowing drawing on the screen.



System may crash when uninstalling or upgrading PCoIP Agent on Windows 10 build 1803 and Windows Server 2019 VM | 75664

When uninstalling or upgrading PCoIP agent on an Windows 10 build 1803 or Windows Server 2019 VM, the system may crash.


Reboot the system before uninstalling or upgrading PCoIP Agent.

PCoIP Agent fails to start | 72726

The PCoIP Agent requires port 60443 for proper operation. Unavailability of this port prevents the agent from starting.

The following PCoIP Agent log message can appear: AGENT :0894 Failed to bind required address ssl:// Cannot bind to port


Reboot the machine.

PCoIP Agent refuses connection with licensing error | 72286

The Windows Management Instrumentation service can run into a bad state, which prevents PCoIP Agent from checking out a valid license. When this problem occurs, user will see the "no license" error on the client and should see the following error message in the PCoIP agent log: {code:java} Exception caught ( Error processing FNE capability response: [1,7E2,5,0[7000001B,0,C03F9]]  Response does not match system hostid. ) while sending a request for license renewal.{code}


This problem was caused by WMI's inability to get host UUID. When running {code:java} wmic csproduct get UUID Node - TERVDIW10DEV22 ERROR: Description = The paging file is too small for this operation to complete.{code}

The workaround is to restart Windows Management Instrumentation and PCoIP Agent for Windows service in sequence in Control Panel -> Administrative Tools -> Services. If the services won't restart then restarting Windows will resolve the issue.

First connection fails to connect after Windows update | 72116

After initiating certain Windows Updates, the update process may not complete until a user attempts to logon.  In these situations the PCoIP session will fail to establish while the Windows Updates completes and the WDDM driver is re-configured.

Subsequent connection attempts after the Windows Updates completes are successful.


Attempt to login via PCoIP after a Windows 10 update. If the connection fails, then wait a few minutes for Windows Update to complete and for the PCoIP agent to restore its compoents and then re-connect.

Windows privacy settings can block microphone access | 72039

Starting with Windows 10 1803, modern applications that attempt to access the microphone can be prevented from doing so.


Through Windows Microphone privacy settings you may need to enable access to the microphone and allow the desired application to access it.

PCoIP Agent upgrade fails due to failure to uninstall the display driver | 71940

A failure to upgrade the PCoIP Agent software includes the following error message in the logs:

ERROR:  An error occurred while uninstalling driver package 'C:\Program Files (x86)\Teradici\PCoIP Agent\drivers\Display\x64\tera_kmdod.inf' (Error code 0x57: The parameter is incorrect.)
  1. Issue the following command:
c:\Program Files (x86)\Teradici\PCoIP Agent\drivers\Display\x64> pnputil.exe -i -a tera_kmdod.inf 
  1. From the windows device manager, uninstall the Teradici PCoIP WDDM driver.

  2. Reboot the VM.

  3. Run the PCoIP Agent installer

Wacom Cintiq 22HD does not work with Cloud Access Software | 71924

Wacom Cintiq 22HD does not work with Cloud Access Software PCoIP Agent for Windows.


Use a Wacom Intuos Pro tablet instead of the Cintiq display model.

Wacom tablet PTH-451 not detected | 71425

Wacom tablet PTH-451 may not be detected correctly when USB bridged to Cloud Access Software Agent for Windows with PCoIP software client for Windows. Software client for macOS and PCoIP Zero Clients work as expected.

Windows INK cursor location not updated | 70173

When USB bridging a Wacom tablet to a Windows agent the cursor position is not updated while working in Windows INK.


Starting with PCoIP Agent 2.15 and when using Zero clients with a minimum firmware of 6.2.0.a2, Teradici recommends using local termination for the Wacom tablet.  This allows the cursor to be properly displayed in Windows INK.

Windows Interactive logon text interferes with PCoIP session connection | 69794

Configuring Windows logon text will cause a PCoIP user to be unable to connect using the PCoIP client.  This is because the Single Sign-On implementation within PCoIP needs to be able to authenticate directly to the user desktop.


You can either disable interactive logon text or you can disable the PCoIP SSO.

Installation timeout in Windows 7 when system restore is enabled | 67818

If system restore is enabled, PCoIP agent installation on windows 7 platform might fail due to time out.


Disable system restore

Windows CardSpace interferes with PCoIP | 66833

On Windows 7 and Windows Server 2008R2 there is a Microsoft feature to support digital identification called Windows Cardspace. Use of this feature will freeze your PCoIP session and prevent future connections.


If you are unable to connect to your PCoIP session due to launching Windows Cardspace then you can connect to your virtual machine using RDP and close Windows Cardspace to re-enable PCoIP connectivity.

Cloud Access Software indicates no license | 66566

Connection via PCoIP can fail stating a lack of license even though the system is properly licensed.  Additionally, issuing the pcoip-validate-license.ps1 command can fail resulting in a crash dump.


Rebooting the VM can restore proper licensing functionality.

PCoIP validate license reports unsupported version of Trusted Storage | 66075

When executing pcoip-validate-license on either Windows or Linux an error is reported stating that 

This version of trusted storage is not supported.
  1. Delete the contents of C:\ProgramData\Teradici\PCoIPAgent\licensing\5 in Windows, or /var/lib/pcoip-agent/licensing/5 (requires root permissions) in Linux

  2. Restart the appropriate agent service (PCoIP Graphics Agent or PCoIP Standard Agent on Windows, or pcoip-agent on Linux)

  3. If using Teradici Cloud Licensing (not using a local license server), re-register the host.

Licensing can fail if Windows WMI infrastructure is impaired | 65660

Windows infrastructure failures can prevent PCoIP agent licensing to be acquired. If the PCoIP agent is not licensed, the user will not be able to connect to the remote machine.


Rebooting the machine may resolve the WMI impairment, enabling PCoIP licensing to be successfully acquired.

PCoIP connection may be blocked by existing RDP sessions | 63331

When using Windows Server without the RDS role installed, Windows will only support two concurrent user connections at most. If a third user attempts to initiate a PCoIP session, that login will be blocked, requiring the user to disconnect one of the other two sessions. This disconnect requires the user to have administrative rights on the machine.


Do not attempt to connect more than two users to a Windows Server system that does not have the RDS role installed.

Invalid resolution when hotplugging monitors | 59421

If two different monitors are used and one or more displays is removed or added during a PCoIP session, there is a chance that one of the displays may get an incorrect resolution.


Disconnect your PCoIP session and reconnect.

Windows Filter Keys are not supported for Windows 10 and Server 2016 | 55978

Enabling Windows Filter Keys will render user unable to unlock desktop.


Disable Windows Filter Keys.

Operating system re-installation requires re-installation of PCoIP Standard Agent | 54456

Upgrading from Windows 10 to Windows 10 Anniversary Update (1607) performs an operating system re-install. After re-installing Microsoft Windows, only some device drivers are migrated to the new operating system. Since not all of the PCoIP Standard Agent software is migrated, it will need to be re-installed.

Performance counters do not appear to collect data | 45092

In some cases, even though the performance counters have been installed correctly, it may appear as if they are not collecting data. This occurs due to the fact that the user may have opened the 64-bit version of the performance monitor, while Teradici's performance counters are 32-bit only. As the counters cannot be loaded into the 64-bit version, Windows will disable data collection. A corresponding message in the Windows Event Log should indicate this as well.


To solve the issue: 1. Click Start, click Run, type cmd, and then click OK. 2. Type the following command, and then press Enter: mmc.exe /32 perfmon.msc. This command runs System Monitor in 32-bit emulation mode. 3. Use System Monitor to determine whether the performance counter object is available.

Relative mouse is not supported by PCoIP agent | 44176

Relative mouse is not supported by PCoIP Standard Agent, Graphics Agent, or Multi-Session Agent. The 'Relative mouse enabled' message does not display in client logs.

System volume set to maximum after agent upgrade | 42226

When upgrading to the latest PCoIP agent, audio volume is automatically set to maximum.


Manually set the audio to the desired volume after upgrading. Once set manually, the audio volume is maintained. The change in audio volume only happens at upgrade.

PCoIP agent fails to connect when host has multiple NICs | 40825

When a host computer has more than one network adapter, the system must be configured to inform which adapter to use for inbound PCoIP connections. You can do so by populating the PCoIPConnectionAddress registry value with your desired network interface.

Some software applications such as Npcap can create a virtual network adapter that will present additional Ethernet adapters. These configurations also require populating the PCoIPConnectionAddress registry value with your desired network interface.


In HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Teradici\PCoIPAgent, set the PCoIPConnectionAddress registry value:


Where a.b.c.d is your desired network interface). The type of the reg key is a string value: REG_SZ.

Agent installation may take a long time | 22702

Teradici installs Microsoft Visual Studio 2013 C/C++ runtimes as part of the agent installation. Runtime installers create a system restore point which, on systems such as Windows 8, can take over 15 minutes. If the installer appears to be stalled when installing the C/C++ runtimes, it may simply be the runtime installers creating a system restore point.
