Citrix Receiver Web App

Posted By admin  On 30.04.21



Exit Citrix Workspace App or Citrix Receiver and launch it again; Note: Changes made to the above file will be applied to all the connections. ChromeOS: On ChromeOS there are two ways of switching between applications/windows within a Citrix Desktop Session, see below: Go into full screen mode on your Citrix Desktop Session. From StoreFront in C:inetpubwwwrootCitrixRoamingweb.config; Published App Keywords (e.g. Prefer or mandatory). Receiver 4.5 and newer supports published app Delivery configuration for adding the shortcut to the desktop. This only works if the app is a Favorite.

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

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.

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.

downloadWhy can't I download this file?

Solution

In recent releases of IE, Edge, Google Chrome, Firefox, and latest Citrix Workspace App clients many of the issues mentioned below have been resolved.
By default, the OS (Windows, Mac, Linux) should automatically set how to open '.ica' files when trying to launch any resource via Citrix Workspace or Citrix Storefront via the Web Store if the Citrix Workspace App is installed properly.
Confirm Citrix Workspace App is installed or use Citrix Workspace App for HTML5 ('Web Browser' option) instead.
If you continue to encounter this behavior please review the steps outlined below.

There can be a number of resolutions to the issue including but not limited to the following:

Associate .ica File Type With Citrix Connection Manager

  1. On Windows computers, go to Control Panel > Settings > Apps > Default apps > Choose default apps by file type

  2. Under Name, find .ica file type.

  3. Ensure that the current default is set to Citrix Connection Manager. If not, click Change program and choose Citrix Connection Manager.

Note: Connection Manager is the wfcrun32 file located as C:Program Files (x86)CitrixICA Clientwfcrun32.exe

Remove or Disable Third Party Browser Adware

Remove or disable any third party browser based Adware software that could be interfering with the successful launch of the ICA file. Restart the browser after removing these software and try again.

Clear the 'Do not save encrypted data to disk' Option

If you are using Internet Explorer, click Tools > Internet Options > Advanced tab and clear the option “Do not save encrypted data to disk.”. This option should be cleared because the dynamic files are stored in the Temporary Internet Files folder. When applications are clicked, a file is downloaded to the folder, then launched using MIME type. If access to the folder is disabled or not available, the process cannot occur successfully.

Below are for older Browser/Citrix Receiver Deployments:

No longer recommended to perform these steps in newer releases of Internet Browsers. Steps remain for any users not fully updated to the latest and greatest.

Add Website to Trusted Sites

Add the site to the Trusted sites list if using Internet Explorer browser using the following steps:

  1. Go to Tools > Internet Options > Security tab > Sites

  2. In the Add this website to the zone field, enter your organization's website and click Add.

  3. Repeat this for the .com, .net, .org, or .gov Web site addresses of your organization to allow the use of the ActiveX ICA client object for the launched connection to be automatically accepted.
    Note: It might be required to also add any additional subdomain.domain.com URLs to the Trusted sites list in the Security tab setting if still experiencing unwanted prompts.
