I had same problem as you. Actually when my computer came brand new I already had this error showing in event log.  I tried everything.. Uninstall, download from Dell and install. Or even tried installing through windows store and didn't work.  After struggling for so long, I think I figured it out.  Open services.msc, look for AWCCService and change delay start to automatic.  I think it is the timing of the boot up of the Alienware command center that is falling behind before the service started. Or the service is having conflict with using delay start.    For those that don't see error.. Look carefully.. It may show up as warning instead and windows error report is sending the report to Windows about it.       
Each time I reboot I have same error, making AWCC sometimes slow to start. Any idea ?
