Citrix Workspace App 1912 CU1 Taskbar office apps disappear - moved to tombstones

[Björn Schläfli]

Hi all

 

we've updated Citrix Workspace 1907 to 1912 CU1. Some of our customers report now that pinned office Citrix published apps disappear from their taskbar. It affects only office applications, e.g. Google Chrome and others pinned to taskbar are kept. While analyzing this I've noticed that the office links are moved from %APPDATA%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar to a subfolder called Tombstones. I've never heard about that.

It happens while users are working or if they relogin to their computers or if they restart their computers.

 

Tested with no luck so far:

Reset Workspace App

Reinstall Citrix Workspace App

created a new local Windows 10 user profile

 

 

Any ideas?

 

Edit:

I have tested a bit more.

It only affects applications with file type association (content redirection), which are office applications in our site. And it's not happening with Citrix Workspace App 1907. As soon as I click refresh on Workspace App or do a selfservice.exe -poll the fta icons disappear. Procmon shows Selfservice.exe as the one who removes these links in taskbar.

Difference between non-fta and fta icons is:

non-fta command line -> "C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\SelfService.exe" -launch -reg "Software\Microsoft\Windows\CurrentVersion\Uninstall\....

fta command line -> AppData\Roaming\Citrix\SelfService\MicrosoftWordCitrix.exe -startmenuShortcut

I've called Citrix and they delivered me a privat fix (replace SelfService.exe and InstallerLib.dll in SelfServicePlugin directory).

The fix is scheduled for 1912 CU3 and new CR release as Citrix told me.

more tests done.

 

Selfservice.exe removes all fta icons from taskbar with version 1912 and up.

reg key reusestubs not helping.

Tested old workspace app 1909 and 1911. Pinned icons are kept with them. The issue starts with workspace app 1912 CU 0.
