Mike Stacy writes “ Side-by-side error when running DHCPUtil.exe with Lync Server 2010”

Posted by Mino on November 4, 2010


In trying to run DHCPUtil.exe from your Windows Server 2008 x64 DHCP server with the appropriate command line parameters in order to configure DHCP for Lync Server, you may run across the following error:

The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.

Reviewing the app log reveals the following:
