Citrix Desktop Viewer

Posted on  by admin

Introduction and the problem

After installing some applications, Windows restarts and when we try access via Citrix Virtual Apps and Desktop a gray screen appears, without the desktop, without apps without the possibility of doing something.

  • I started messing around with Citrix preferences and settings. When you connect to the remote machine via Citrix on top of the Desktop Viewer there some configurations settings, but unfortunately it didn’t let me get very far. Copy and Paste was disabled and I could not drag and drop files.
  • Users can override this by choosing the HDX Generic USB Direction from the Desktop Viewer preferences tab or enabling it by administration through Citrix policies. Citrix is stating that General USB direction should be used when there are application compatibility.
  • The Citrix Workspace app allows for secure, unified access to all of your SaaS apps, web apps, virtual apps, files, and desktops. If your company uses Citrix, simply login with your company credentials to access all of the resources you need to be productive from anywhere.

If we check the event viewer, everything fine, without errors and it show that ICA-HDX logs being local or external, it is waiting for connections

Event ID 1003 – TdIca – The Citrix ICA Transport Driver is no longer waiting for connections on port 1494.

Open the web.config file, and modify the setting showDesktopViewer to ' On' or ' Off' to disable or enable Desktop Viewer. Each StoreFront store has two web.config files, one for the services site and one for the website. The web.config file location on StoreFront is.

In some cases, if we trying to uninstall the Agent or Install the VDA agent does not throw this error

Product: Citrix Monitor Service VDA Plugin — Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: CompileResourceUtilizationMOF, location: C:Program FilesCitrixVirtual Desktop Agent, command: mofcomp.exe “Citrix_ResourceUtilization.mof“”

The solution to the gray screen

For some reason, be it the installation of software or user error, the systems environment variables were modified, in particular the Path variable

If we edit the Path variable. it must show %systemRoot% and HDX paths

Then it’s just a matter of restarting and testing

The preceding issues can be avoided by preventing the Desktop Receiver toolbar or the Desktop viewer toolbar from appearing when users access XenApp farms that deliver published desktops.

To prevent the display of the Desktop Receiver toolbar, edit the Web Interface site configuration file.

Complete the following procedure to edit the Web Interface site configuration file:

Citrix Desktop Viewer Windows 10

  1. Using a text editor, open the WebInterface.conf file in the conf folder for the site. The default location of the conf folder is, C:inetpubwwwrootCitrixSiteNameconf.

  2. Add the following line in the file. Farm1, Farm2, Farm3, and so on, are the names of the farms for which the Citrix Desktop Toolbar should not appear:
    FarmsWithNoConnectionBar=Farm1, Farm2, Farm3, ...

  3. Using a text editor, open the file. The default location of this file is C:inetpubwwwrootCitrixSiteNameapp_codePagesJavacomcitrixwipagessite folder.

  4. Locate the following code in the file around line number 181:
    ICAFile icaFile = generateIcaFile (userContext, launchInfo);

  5. Add the following code after the preceding line:

    Add the following code in the file for Web Interface versions 5.1, 5.2, and 5.3:

    Add the following code in the file for Web Interface versions 5.4. When compared to the preceding code, the last line changes, as shown in the screen shot:

  6. Save and close the files.


In addition, you can configure the following to ensure that the Desktop Viewer bar is always used for XenDesktop session while you have implemented the preceding change for a single Web Interface site that contains both XenDesktop farm and XenApp farm.
