Try this link for a version for the R7 UK Link [URL]  US Link [URL] 
Hello, For the life of me I can not find the software download link for the Aurora R7's AWCC (Alienware Command Center) equivalent. The AWCC 5.2.42.0 does not work with the Aurora R7<ADMIN NOTE: Broken link has been removed from this post by Dell>. Entering in my service tag no compatible versions are found. I do have SupportAssist and ran it, it does not try to download anything like this from Dell.I reformatted my PC and would like to turn off all of the external RGB lights on my PC and not being able to find the proper software is a pain. Thanks in advance for any tips. 
Aurora R7, RGB Controller, AWCC
