Office 2021 LTSC Click-to-Run crashing Citrix server

Hi,

We have deployed Office LTSC 2021 32bit Click-to-Run on a Windows Server 2016 Citrix server. When two different users launch the application, RDS stops working on the server and it is no longer responsive. We have used KMS activation and installed through CDN.

We are running Citrix LTSR 7.15 and the previous version of Office that is working is Office 2013 Click to Run, KMS Activated.

Any advice on why this is continually crashing RDS?

Thanks

Hi @MARTINNicole-1410,
Did this problem only appear with launching Office? How did you launch Office? Did you test all Office programs? Excel, Word, PowerPoint ect..?
I suggest you open it in safe mode running the following command: Press Win + R, type "excel /safe" in the blank box, press Enter. If it works fine in safe mode, please check the add-ins in your excel and disable them.
Click File > Excel Options > Add-Ins on the left side of the dialog. Then click the drop-down arrow at the bottom of the dialog box and select "COM Add-Ins" from the list, then click the GO button. What comes up is a list of COM-Add Ins that are loaded and running.
If the issue still exists in safe mode, I suggest you to collect the event log and provide us with the whole error messages of event log.
You can refer to this support article: https://docs.microsoft.com/en-us/windows-server/storage/folder-redirection/troubleshoot-user-profiles-events

Hi @emizhang-msft
The problem only appears for Office 2021, we have tested Excel, Word and Access as they are the only products we require. Office was launched via a Citrix published application.
As for COM Add-ins, we have Inquire, Microsoft Power Map for Excel, and Microsoft Power Pivot for Excel.
The published applications are working in Safe Mode, so I am looking at disabling the “COM Add-Ins” as per your advice for testing.
Thanks for the help.

Hi,

It appears it was a Citrix issue all along.

This has now been resolved. The issue was that the Virtual Delivery Agent was not applying the Workspace Environment Management (WEM) security settings that were set in the servers Configuration Set in WEM. This meant that all processes were being blocked on launch and not allowing applications such as Office to work correctly. It was blocking dwm.exe which caused the RDS issue, and in turn, was applying AppLocker settings to the server as a whole.

I had to open and resave the policies and then they applied to the machine.

Thank you for all help provided.

Thanks
