You see only a white screen when viewing Lync 2013 desktop sharing

Hi guys,

A few weeks ago someone was sharing with me his desktop and I was able to see only a white screen like the following:

WhiteAppSharing

Seems that the failure is on the client computer and it is related to ActiveX Security settings in IE.

To fix this you need to open PowerShell in administrator mode in order to change registry settings and execute the following commands (depending on your Windows version)

  • Setting the compatibility mode for Lync 2013 64 bits or running Lync 2013 32 bits on Windows 8 32 bits
    • Set-ItemProperty -Path “HKLM:\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}”-Name “Compatibility Flags” -Value 8388608
  • Setting the compatibility mode for Lync 2013 32 bits on Windows 8 64 bits
    • Set-ItemProperty -Path “HKLM:\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}”-Name “Compatibility Flags” -Value 8388608
  • All you need to do is restart the application sharing session and the issue should be resolved, no need to restart client or computer
