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.

• Citrix Virtual Apps software uses FlexCast Management Architecture (FMA), a proprietary architecture for Citrix virtualization products. It delivers individual applications, as opposed to entire desktops, to devices. It is also used with Citrix Workspace to deliver apps as part of a complete virtual desktop environment.
• The new Citrix Workspace app (formerly known as Citrix Receiver) provides a great user experience — a secure, contextual, and unified workspace — on any device. It gives you instant access to all.
• VMware Workspace ONE UEM 2005. Workspace ONE UEM On-Premises High Availability 56.

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:

Citrix Workspace provides secure access to virtual desktops, applications, and Information Technology (IT) services from various platforms and devices. This technology enables users to manage enterprise data, applications, and desktops through secure, centralized deployment to any user device. Citrix acquired Sequoia Software Corp. In 2001 and ExpertCity, a provider of remote desktop products, in 2003. This was followed by more than a dozen other acquisitions from 2005 to 2012, which allowed Citrix to expand into server and desktop virtualization, cloud computing, Infrastructure as a Service, and Software as a Service offerings.

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

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.

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.

Avoid Citrix receiver not launching applications issues for good with Parallels RAS

To avoid Citrix Receiver application launch issues for good, shift to Parallels® Remote Application Server (RAS). Parallels RAS is a virtual application and desktop delivery solution with a much simpler architecture. Complex issues like those mentioned above are eliminated from the client-side and can usually be addressed by simply reinstalling or restarting the Parallels Client. In addition, users can also switch to the HTML5 Client until any issue is resolved.

Citrix Workspace App 2005 For Windows

Don’t just take our word for it—try it out yourself. Download your 30-day Parallels RAS trial now and say goodbye to all your application launch issues.

Citrix Desktop as an IT term

You’ve probably heard a few IT folks mention the term ‘Citrix Desktop’. What exactly is it? How is it different from ordinary desktops? We will talk about that and more in this post.

What exactly is Citrix Desktop?

When people use the term ‘Citrix Virtual Desktop’ they’re usually referring to a virtual desktop delivered through the Citrix Virtual Apps and Desktops environment, a virtual application and desktop delivery solution formerly known as XenDesktop.

Citrix Virtual Apps and Desktops offers IT staff full control of applications, machines, and security for end devices, regardless of their operating system and interface. It installs and manages the following components:

• Delivery Controller: The central control layer of a Citrix deployment used for user access management, connection management, and distribution of desktops and applications.
• Citrix license management: Communicates with the controller to manage user session licensing and allocate license files.
• Citrix Studio: The management console that helps manage and configure delivery groups, catalogs and connections.
• Citrix Director: Enables IT support and help desk teams to troubleshoot issues, monitor environment, and perform support related tasks.
• Workspace configuration: Configure services to be integrated with Citrix Workspace, customize URLs, customize the appearance of subscriber workspaces, and specify external connectivity for resource locations used by subscribers.
• Citrix StoreFront: Predecessor of the Citrix Workspace, it allows subscribers to access apps, authentication, desktops, and data to ensure consistent experience on all connected devices.
• Citrix Gateway: Provides a single point of access to let users connect to the system from outside the corporate security system.

Basic functions of a Citrix Desktop

Unlike a regular desktop that runs locally on a computer, the elements of Citrix Desktop run on a remote host. This allows the virtual desktops to be delivered not only to PCs, but also to tablets, smartphones, thin clients, and other devices. A single desktop image can be used to provision virtual desktops to many users with similar desktop requirements. That can be useful in organizations looking to support things like BYOD (Bring Your Own Device) and telecommuting as well as use cases involving thin clients.

The only requirement on the device side is that it should be running the Citrix Receiver, a piece of software responsible for managing the virtual desktop on that device. While you can continue to download older versions of Citrix Receiver, it has now been replaced by the Citrix Workspace app. Citrix Workspace app supersedes Citrix Receiver, but is fully backward-compatible with your existing Citrix infrastructure while offering new capabilities.

Management and control

Management and control operations for Citrix Desktops are carried out in two places: Citrix Studio and Citrix Director. Citrix Studio is where you would set up, configure, and deploy the virtual application and desktop environments. Citrix Directory, on the other hand, is where you would conduct administration, monitoring, and reporting.

Major issues of Citrix Desktop

Most companies who have tried using Citrix Virtual Apps and Desktops will tell you this: 1) It’s complicated to set up and manage, and 2) it requires a considerable capital outlay. It’s not a wise investment, considering there’s a much better alternative. It’s called Parallels Remote Application Server (RAS).

Why Parallels RAS is a better alternative

Parallels RAS has all the capabilities of Citrix Virtual Apps and Desktops but can be purchased at a fraction of the cost. In addition, it’s much easier to install and manage. For example, if you talk about administration, Parallels RAS has only one console for setting up, configuration, deployment, administration, reporting, and more.

The Citrix infrastructure alone is many times more complicated. Before you can start rolling out Citrix Desktops, you’ll need to overcome the intricacies of various components like Delivery Controllers, Studio, Director, StoreFront, NetScaler, and so on. The licensing is also very complicated.

Parallels RAS is much simpler. It’s a single product with a straightforward licensing structure.
