A colleague has an issue with an xbap Application: When accessing the URL, the following message appears
Startup URI: https://app.service.url/App.Client.xbap
Application Identity:
The download of the specified resource has failed.
-----------------------
PresentationHost.exe v4.0.41210.0 built by: Main - C:\Windows\SysWOW64\PresentationHost.exe
ntdll.dll v6.1.7600.16385 (win7_rtm.090713-1255) - C:\Windows\SysWOW64\ntdll.dll
kernel32.dll v6.1.7601.18015 (win7sp1_gdr.121129-1432) - C:\Windows\syswow64\kernel32.dll
....
When I set up a WebEx session and he enables Screensharing, the download succeeds and he can access the application. But as soon as he ends the screensharing, the download starts to fail again. A cleanup of the cache does not help via rundll32 %windir%\system32\dfshim.dll CleanOnlineAppCache
He is trying to access the application in a Citrix environment to have access to the company network.
I tried to find out which settings the WebEx Screensharing changes, but without success.
Here are a few details:
- IE 11.0.9600.18762
- Compatibility Mode: Enabled
- Access via https
Currently I am trying to get the application download to fail on my machine. The things I have tried so far (but did not reproduce the error):
- I have read that WebEx changes the Protected Mode-Setting, so I enabled and restarted my machine
- Switch settings to disabled via "Settings -> Internet Options -> Security -> Custom Level..."
Any input on how to tackle this issue, or the settings which are changed via WebEx screensharing would be very helpful.
Modify this GPO and you should be good to go:
User Configuration\Policies\Administrative Templates\Windows Components\ Internet Explorer\Internet Control Panel\Security Pages\Advanced Page\Do not save encrypted pages to disk.
