I was really excited for Windows 10, but my system was factory reset, so I had to go back to Windows 8.1. By the time I got back to Windows 8.1, I installed all 100-something updates, hoping Win10 or some prerequisite for it would install. I still have not, seen any sort f update for Windows 10. In fact the only update I see currently is a security update for Internet Explorer. I said, ok, I hear there is an ISO I can download. I thought, ok, I just download xxx.iso, run it, Windows would mount it, and I would be on my way o installation. But of course no. Microsoft wants to make things hard. I had to download some media creation tool that would either allow me to install Windows 10 right now, or make a bootable disk. This would be ok, except for the fact that it does not even start. I get a message box saying:
Setup couldn't start properly. Please reboot your PC and try running Windows 10 setup again
I have tried rebooting several times. Each with no more success. I have tried both 32 and 64 bit editions and both fail. How can I fix this. Everything on Google has been telling me to clean u disk space and I cleared ~40Gb using cleanmgr. I have 407Gb available right now.

I found out that the installer was failing due to an earlier attempted installation of Windows 10 that failed (my computer died). In order to fix this, you enter the C:/ drive, show hidden folders, and delete the following:
Note that you may have to enter safe mode to be able to delete some of these.
