This is the error that is thrown by our automated build suite on Windows 2008, while running ICEs (after migrating from WiX 2.0 to WiX 3.0):
LGHT0217:
I faced the same problem and did not like to suppress ICE validation. My setup: I used my own computer as a build agent on Visual Studio Online (VSO). My solution was to change the account used to run the service on my machine. Instead of using Network Service or Local Service I simply made the service log on with my own account which had all the necessary rights.
