Windows 8.1: HDX Engine crashes trying to call GetDpiForWindow function


Connie Webb

Question

Is windows 8.1 really supported?

 

Apparently HDX Engine is trying to call GetDpiForWindow function. According to MS docs GetDpiForWindow it's available from Windows 10 1607. Citrix compatibility matrix tells Workspace App 2204 is supposed to support Windows 8.1.

 

Actually, the last version that works correctly I know of is 2109. Both 2204 and 2112 are not working correctly in Windows 8.1. 

 

For the record, here's an entry from event log:

Faulting application name: HdxRtcEngine.exe, version: 15.31.0.15, time stamp: 0x61a55546
Faulting module name: ocal\Citrix\ICACLI~1\webrpc.dll!GetDpiForWindow, version: 6.3.9600.17415, time stamp: 0x54504b0d

Hi.
We have the same problem with Windows 8.1.

Teams HDX optimization shows "Citrix HDX not connected"
Uninstalling Workspace App 2204 and installing 2109.1 fixed the problem on Windows 8.1. 
It seems that WSA 2202 is also affected on Win8.1
