I have been unable to complete the install od Windows 8 Trial upgrade to 8.1. I have tried using the .ISO download as well as a direct download from Windows store.
Each time, after restarting, I receive an error code. From the Store attempt, the error code was0xC1900101-0x4000D. The .ISO gave a similar error code, but I did not record it. Each time, after the error, the system reverts to it former settings.
I have been unable to find an explanation for the code.
Any help would be appreciated,
