Workspace App dont work with Safari 12

After upgraded to Safari 12, Citrix Workspace App and Citrix Receiver do not start *.ica files any more.

To correct this problem, you need to change the web.config on all Storefront servers.


For StoreFront deployments, modify web.config under the Receiver for Web (RfWeb) site (typically C:\inetpub\wwwroot\Citrix\StoreWeb) to activate the Citrix Receiver Launcher / Citrix Workspace App Launcher for Safari 12 and later.

1. Open web.config using your preferred text editor and locate the line : <protocolHandler enabled=”true” platforms=”(Macintosh|Windows NT).*((Firefox/((5[2-9]|[6789][0-9])|\d\d\d))|(Chrome/((4[2-9]|[56789][0-9])|\d\d\d)))” skipDoubleHopCheckWhenDisabled=”false” />

2. The value of the platforms attribute is a regular expression specifying the browsers that Citrix Receiver Launcher is used for client detection and HDX launches. Change the regular expression to:

“(Macintosh|Windows NT).*((Firefox/((5[2-9]|[6789][0-9])|\d\d\d))|(Chrome/((4[2-9]|[56789][0-9])|\d\d\d)))|Macintosh.*Version/(1[2-9]|[2-9][0-9]).*Safari/

3. This will add Safari 12 and later to the list of browsers that Citrix Receiver Launcher will be used.

How to Reset StoreFront to the Initial Factory Settings

Last week i got some problem with a Storefront server and wanted to reset back to start.

Found this brilliant article from Citrix that I want to share with you:

  1. Open a PowerShell command prompt as an Administrator and type   asnp Citrix*   
    This loads the Citrix PowerShell modules.
  2. Ensure that the StoreFront Management console is closed.
  3. From the command prompt type . “C:\Program Files\Citrix\Receiver StoreFront\Scripts\ImportModules.ps1”
    : Ensure to include the leading period in the Powershell command.
  4. After the modules are imported type Clear-DSConfiguration.
    This will reset Storefront to its factory state.
  5. When you have run the command and it has completed successfully, open the StoreFront Management console and confirm that all settings are reset. The option to Create a new deployment or Join existing server group will now be available.
