I am trying to upgrade from Beta 2, Build 5384 to RC1. Every time I try to upgrade i get this error which occurs somewhere in the copying files stage of installation:
Windows cannot copy files required for installation. The files may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070017
First I thought it may have been a fault when writing the image to DVD, so I burnt another one, same problem. I then, instead of upgrading when already in Vista, I tried a clean install of RC1, exact same problem.
Now beginning to get quite frustrated, I downloaded the file again; same problem.
I have now formatted hard-drives, tried every combination of installing Beta 2, upgrading to clean installs of RC1 and I get the same error each time.
