Citrix Receiver for Windows provides users with secure, self-service access to virtual desktops and apps provided by XenDesktop and XenApp. Apart from using the windows receiver interface, users can also use the receiver with storefront from the website.

Secure User Environment

To maximize the security of the environment, the connections between Citrix Receiver for Windows and the resources you publish must be secured. You can configure various types of authentication for Citrix Receiver for Windows software, including smart card authentication, certificate revocation list checking, and Kerberos pass-through authentication.

1. Configure domain pass-through authentication

To enable domain pass-through using the graphical user interface:

1. Locate the Citrix Receiver for Windows installation file (CitrixReceiver.exe).

2. Double click CitrixReceiver.exe to launch the installer.

3. In the Enable Single Sign-on installation wizard, select the Enable single sign-on checkbox to install Citrix Receiver for Windows with the SSON feature enabled. The image below illustrates how to enable single sign-on:
   

2. Configure domain pass-through authentication with Kerberos

Citrix Receiver for Windows supports Kerberos for domain pass-through authentication for deployments that use smart cards. Kerberos is one of the authentication methods included in Integrated Windows Authentication (IWA).

When users install Citrix Receiver for Windows, include the following command-line option: /includeSSON. This option installs the single sign-on component on the domain-joined computer, enabling Citrix Receiver for Windows to authenticate to StoreFront using IWA (Kerberos). The single sign-on component stores the smart card PIN, which is then used by the HDX engine when it remotes the smart card hardware and credentials to XenDesktop. A related option, ENABLE_SSON, is enabled by default and should remain enabled.

To apply the settings, restart Citrix Receiver for Windows on the user device. After that, users also need to configure StoreFront:

1. In the default.ica file located on the StoreFront server, set DisableCtrlAltDel to false.
2. When you configure the authentication service on the StoreFront server, select the Domain pass-through check box. That setting enables Integrated Windows Authentication. You do not need to select the Smart card check box unless you also have non domain joined clients connecting to Storefront with smart cards.

3. Configure smart card authentication

a. To enable single sign-on for smart card authentication

To configure Citrix Receiver for Windows, include the following command-line option when users install it: ENABLE_SSON=Yes. Single sign-on is another term for pass-through authentication. Enabling this setting prevents Citrix Receiver for Windows from displaying a second prompt for a PIN.

b. To enable user devices for smart card use

1. Import the certificate authority root certificate into the device's keystore.
2. Install your vendor's cryptographic middleware.
3. Install and configure Citrix Receiver for Windows.
4. Details on certification installation can be found here in - https://docs.citrix.com/en-us/citrix-workspace-app-for-windows/system-requirements.html

​c. To change how certificates are selected

Change how certificates are selected by using either of the following methods:

1. On the Citrix Receiver for Windows command line, specify the option AM_CERTIFICATESELECTIONMODE={ Prompt | SmartCardDefault | LatestExpiry }.
2. Add the following key value to the registry key HKCU or HKLMSoftware[Wow6432Node]CitrixAuthManager: CertificateSelectionMode={ Prompt | SmartCardDefault | LatestExpiry }.

d. To use CSP PIN prompts

Change how PIN entry is handled by using either of the following methods:

1. On the Citrix Receiver for Windows command line, specify the option AM_SMARTCARDPINENTRY=CSP.
2. Add the following key value to the registry key HKLMSoftware[Wow6432Node]CitrixAuthManager: SmartCardPINEntry=CSP.

4. Enabling certificate revocation list checking

When certificate revocation list (CRL) checking is enabled, Citrix Receiver checks whether or not the server’s certificate is revoked. By forcing Citrix Receiver to check this, users can improve the cryptographic authentication of the server and the overall security of the TLS connection between a user device and a server.

Advanced Preferences

Users can right click on the receiver icon on the toolbar and select Advanced Preferences to view an advanced preferences list like the picture below.

1. The Citrix Connection Center displays all connections established from Citrix Receiver. The Connections window displays a list of active sessions. Each server entry in the list represents a session. For each seamless session, below each server entry, a list of the hosted resources you are running on that server appears. The Connection Center offers various options to view statistics and control sessions and applications.
   

2. Resetting receiver will delete all apps, desktops, accounts and configurations, and will return receiver to default settings. It will also close all active sessions. This feature will only be used to serious problems.

3. When users click Settings Options in the advanced Preferences menu, users then will have 2 tabs. Users can choose the application display settings and reconnect options in this two tabs.
   

4. If users delete the passwords, users are asked for the password the next time they log in.

5. Data collection is designed to ask users whether they agree to send anonymous data and usage statistics to Citrix, which help Citrix to provide better products.

6. Starting with Release 4.5 of Citrix Receiver for Windows, Configuration Checker helps users to run a test to ensure Single sign-on is configured properly. The test runs on different checkpoints of the Single sign-on configuration and displays the configuration results.
   

When users log in to the Citrix Receiver for Windows, users can launch a published desktop session. From the Desktop Viewer toolbar, users can select Preference to configure some preferences.

1. When click File access, users can choose the way that they want to use to access files on the computer. It contains 4 ways: read and write, read only ,no access and ask me each time.
   

2. When comes to the connection part, users can choose how devices, including microphone, webcam, digital camera and scanner, will connect to the virtual session. Also, there is a Relative Mouse setting providing an option to interpret the mouse position in a relative rather than an absolute manner. This capability is required for applications that demand relative mouse input rather than absolute.
   

3. The display part provides a choice about the way the virtual desktops display. We recommend our users to use the Best Resolution since this kind of resolution will fit the screen perfectly automatically.
   

4. The flash part provides a choice about whether user want to optimize the content of flash player. If users optimize content, the playback quality will be improved but the security will be reduced. If not, just basic playback quality will provided but with high security.
   

A typical Citrix environment can be so complex. What might seem like a simple problem in the Citrix Receiver can turn out to be very hard to troubleshoot. For instance, if a user’s Citrix Receiver is not launching applications, you need to consider a number of factors.

A lot of the solutions involve editing the Windows Registry—a high-risk operation that, if done wrong, can have serious consequences.

Citrix Receiver not Launching Applications: Misconfigured LogoffCheckSysModules registry value in HKLM

When published applications don’t launch and the user doesn’t see any error message, then admins don’t see any entry that stands out in the Event Log of your Citrix server. One of the places you’ll want to check is the value of LogoffCheckSysModules. This is found in the registry subkey:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCitrixwfshellTWI

The value of this registry key SHOULD NOT contain the executable for the application the user is attempting to launch. If the name of the executable in question is there, create a backup of the registry key and then remove the executable’s name from the key.

Application launch attempts in a published desktop get disconnected

When you attempt to launch a published application from a published desktop, that action may disconnect the session of the published desktop. That’s because Citrix receiver is configured by default to reconnect all open sessions upon launch.

To make the application launch succeed, you need to change the value of the WSCReconnectMode key from 3 to 0 in one of the following:

• 64-bit system: HKEY_LOCAL_MACHINESOFTWAREWow6432NodeCitrixDazzle
• 32-bit system: HKEY_CURRENT_USERSOFTWARECitrixDazzle

Citrix Receiver Web

Application not given enough time to launch

Some launch-related issues occur because certain applications need more time to launch. There are two registry key values you can change that might remedy the problem. Both are in the registry key:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCitrixwfshellTWI

The first is LogoffCheckerStartupDelayInSeconds. Try setting this initially to 10 seconds and then increase by 10 seconds until 600 seconds.

The second one is ApplicationLaunchWaitTimeoutMS. Try setting this initially to 10,000 milliseconds and then increase up to 30,000.

Notice that, for these two registry key values alone, much time can be spent trying out different values. And these are just some of the many possible causes why Citrix Receiver is not launching applications.

Citrix Receiver not Launching in Windows 10

Citrix Receiver for Windows 10 has a list of arguably smart features, however there are several issues that constantly pop-up and prevent Citrix Receiver from launching in Windows 10. For instance, launching Citrix with the regular domain user account fails to launch the desktops and applications. If your Citrix Receiver is not launching in Windows 10, mentioned below are the steps you can undertake to fix these errors.

Use Of Citrix Receiver Software

1. Refresh Citrix Receiver applications.

Click on the drop-down next to your name in the upper-right corner of the menu, and click Refresh Apps.

2. Allocate full permissions to the user count being used.

Assign full permissions for the user account under HKEY_USERUSER_SIDSOFTWARECitrix on the client machine.

3. Download the latest available version to prevent compatibility issues.

Navigate to the Citrix Receiver icon >> Advanced Preferences >> About to check the version. Compare it with the latest available version and download a new one if it does not match.

4. Reset the Citrix Receiver if everything else fails. This might cause accounts, apps, and cached files to be removed.

Navigate to Receiver icon >> Advanced Preferences >> Reset Receiver. A prompt appears, asking if you want to reset the receiver. Click Yes, Reset Receiver and type the URL remote.ptlgateway.net in the popup box that appears next. Enter your credentials again.

Applications not launching on Apple Safari 12

Apple has removed the support for NPAPI, hence Citrix applications now fail to launch in Apple Safari 12. This problem can be solved by carrying out some changes in the server side or the client side. You can modify the web config under the Receiver for Web (RfWeb) site in the server. The client-side change includes enabling the Develop tab at the Safari menu, using which the Safari cache and all Safari Windows are closed prior to starting Safari to browse the Storefront’s receiver.
