Fixed issues

Citrix Director

  • When you navigate to Filters > Sessions in Citrix Director, check boxes are displayed instead of the session data. [LC9871]

  • Custom administrators might not be able to retrieve the session details from a VDA Version 7.15 when the Citrix Director is connected to the Delivery Controller Version 7.6. [LD0134]

  • The integration of NetScaler Management and Analytics System (MAS) with Citrix Director might fail. The issue occurs when any group policy changes or renames the built-in administrator account. Director uses the local administrator account to encrypt or decrypt C:\inetpub\wwwroot\Director\bin..\plugin\hdxInsight\data.xml. This fix addresses the issue while the changes are made in the code. After the changes are made, Director uses the machine account of the machine on which Director is installed to encrypt or decrypt C:\inetpub\wwwroot\Director\bin..\plugin\hdxInsight\data.xml. [LD0231]

  • The Daylight Saving Time (DST) is turned on in the operating system. When you attempt to export data by selecting the CSV format to generate an export report for the previous month, the two radio buttons Export Chart Data and Export Table Data might be missing. [LD0569]

  • Attempts to use the Group Policy Management Console (GPMC, gpmc.msc) to copy a Group Policy Object (GPO) that contains Citrix Policy settings might fail. The Microsoft Management Console (MMC) exits unexpectedly. [LD0322]

  • The Citrix Universal Printer object is created with the EMF Universal Print Driver inside a session even when you set the Universal Print Driver preferences to XPS or Native drivers. To enable the fix, install the Citrix Receiver for Windows 4.9.5000 LTSR Cumulative Update 5 or a later version. [LD0360]

  • When you modify a policy in Citrix Studio, this error message might appear in the Configuration Logging.

    Error while attempting to determine the policy change details.

    When this error message appears, you cannot determine the details of the policy change using Configuration Logging. [LD0596]

  • When a large number of site policies are configured and if the policies have the IP or the OU based filters, there might be a delay in the logon process. [LD0221]

Citrix Studio

  • This release removes the dependency on Version 2.0 of PowerShell in stand-alone deployments of Citrix Studio and its components.

Note: A version of PowerShell continues to be required on the machines where you install one or more of those components, but the requirement is no longer for Version 2.0. On Delivery Controllers and StoreFront servers, PowerShell 2.0 continues to be required. On Windows 7 or Windows Server 2008 R2 systems, Version 3.0 or later of PowerShell is required on the machines where you install Controller components, including Citrix Studio. [LD0184]

  • When you add multiple App-V packages to a site, Studio might display this error message and the administrator cannot publish new applications:

    There was a problem communicating with the server. Get-AppLibAppVPackage : The maximum message size quota for incoming messages (41943040) has been exceeded. [LD0232]

To enable the fix, install the Citrix Receiver for Windows 4.9.5000 LTSR Cumulative Update 5 or a later version. [LD0360]

  • After you rename an application within the application properties and then attempt to remove the Delivery Group from the application in Citrix Studio, this error message appears:

    Object does not exist.

    The issue occurs when the application property ApplicationNameWithFolder uses the old name after you’ve changed the application name, instead of replacing it with the new name. [LD0594]

  • Using the Add Machines wizard to add one or more machines to either an existing or a new Delivery Group might return this error:

    Machine is already allocated.

    The message appears only when you go back to the first wizard screen at least once by clicking the Back button. [LD0924]

  • You might not be able to view machines from other catalogs in a Delivery Group. The issue occurs when you add machines using the Add Machine wizard to either a new or an existing Delivery Group. [LD0988]

  • In a multi-type licensing scenario that is configured for Delivery Groups, an incorrect license type that is not configured for a Delivery Group might be checked out. [LC9086]

  • This release removes the dependency on Version 2.0 of PowerShell in stand-alone deployments of Citrix Studio and its components.

Note: A version of PowerShell continues to be required on the machines where you install one or more of those components, but the requirement is no longer for Version 2.0. On Delivery Controllers and StoreFront servers, PowerShell 2.0 continues to be required. On Windows 7 or Windows Server 2008 R2 systems, Version 3.0 or later of PowerShell is required on the machines where you install Controller components, including Citrix Studio. [LD0184]

  • When a Delivery Group contains at least one VDA in drain-mode, that Delivery Group might not be selected to start a published application. [LD0194]

  • When you add multiple App-V packages to a site, Studio might display this error message and the administrator cannot publish new applications:

    There was a problem communicating with the server. Get-AppLibAppVPackage : The maximum message size quota for incoming messages (41943040) has been exceeded. [LD0232]

  • When using the PowerShell command get-brokericon -filename with the -servername parameter, the command returns an error message. [LD0324]

  • The Citrix Virtual Apps published applications might not enumerate intermittently. As a result, a blank screen appears after the session starts or the applications fail to start. The SQL server might experience high CPU usage and the SQL Monitor might show blocked and expensive processes. [LD0336]

  • The Citrix Universal Printer object is created with the EMF Universal Print Driver inside a session even when you set the Universal Print Driver preferences to XPS or Native drivers. To enable the fix, install the Citrix Receiver for Windows 4.9.5000 LTSR Cumulative Update 5 or a later version. [LD0360]

  • The resource utilization data in Citrix Director might not be sorted in the correct order. The issue occurs when the SQL statements are presented in the wrong order. [LD0388]

  • When you start a session, the broker might choose newly created VDAs over VDAs that were previously started. This choice can cause increased logon time. The increase occurs when the selected VM does not complete the post startup operations before the VM receives a session request. [LD0511]

  • After you rename an application within the application properties and then attempt to remove the Delivery Group from the application in Citrix Studio, this error message appears:

    Object does not exist.

  • When this error message appears, you cannot determine the details of the policy change using Configuration Logging. [LD0596]

  • Citrix Director might show incorrect user connection failures when the FailureDate column for sessions is set to Null in the MonitorData.Session table. As a result of this failure, the failure types are not updated in the MonitorData.ConnectionFailureLog table. There is a mismatch in the connection failure value that is retrieved from the Monitor Database and from the Get-BrokerConnectionLog output that is pulled from the Site database. [LD0726]

  • If the .vhd extension is present in the upper case (.VHD), the VHD picker might not detect it as a valid vhd image. The issue occurs when you create a Machine Creation Services catalog in an Azure environment. [LD0746]

  • The identity disks might be removed from the Machine Creation Services (MCS) that are present in the Amazon Web Services (AWS). [LD1043]

  • When using applicable product releases, the administrator might not be able to create a host connection in Studio if NSX-T networking is enabled in the VMware environment. The issue occurs when the MCS does not enumerate the opaque network in NSX-T. [LD1102]

  • The HDX connection logon data might be missing from the Logon Duration graph. [LD1113]

  • When you change the CreateNewInstanceOnReset setting from false to true and then reset the machine, the updated catalogs might revert.

    With this fix, power cycling does not reset the virtual machines and there is no option to change the setting. [LD1114]

  • There might be a delay of several minutes when you restart a machine while using Amazon Web Services (AWS). [LD1220]

  • The Citrix Monitor Service might consume a significant amount of memory. As a result, the Delivery Controller becomes unresponsive and the call requests made from Director time out. [LD1370]

  • When the CopyFileWithRetries function fails to copy a file in a directory, the remaining files might not be copied. The issue occurs when the Citrix Profile Management service attempts to copy files from a default template profile directory to the current user’s profile directory. During the copy process, the corresponding function CopyDirectory ends the copy operation when one file under the current directory can’t be copied because of permission restrictions. As a result, other files aren’t copied. [LD0648]

  • The VDA for Server OS is running on Microsoft Windows 10, Version 1709 or greater. When you choose to exclude the *.tmp file for synchronization of Profile Management policy, the changes you make to any Microsoft Office documents, such as Word and PowerPoint files, might not be saved while you log out. Your changes are not retained when you log on and reopen the files. [LD0782]
