Windows 8 upgrade installer is not working properly, every time I try to download the OS there is an error "The download task is not complete" "The specified service does not exist as an installed service". I already paid for it, it is pretty irritating that Something I paid for is not letting me install the services it provides. Can anyone help me?

"The specified service does not exist as an installed service" Try enabling the BITS service, WebClient service and Windows Update service; I suspect you have one of them not being able to start so that might be a first thing to troubleshoot. Tell me if it worked so I can put it as an answer. I really suspect it to be BITS because it's talking about a "download task" and that's kind of what BITS does, although its named Jobs there, but that shouldn't matter... – Tom Wijsman Oct 27 '12 at 2:13
I don't know how to enable the bits service. – zach Oct 27 '12 at 2:18
Start > Run > Services.msc > Double click BITS and set it to Automatic, then click Start, then Apply. – Tom Wijsman Oct 27 '12 at 2:26
I set bits to automatic then ran the installer again, yet it still gives me the same error. – zach Oct 27 '12 at 2:34
"I set bits to automatic" but is the status column showing "Running"? also check the other services Tom suggested. – Moab Oct 27 '12 at 2:40

Redownload the Windows 8 Upgrade Assistant. Your download may have been corrupt.
