Hi All, I had installed the W10 Media Center from this forum successfully on my test computer. After stalling for some time, I decided to bite the bullet and install it on one of my Windows 7 recorders (HP Elitebook 8540). The Windows 10 upgrade went well, but the installation of the package (version 6.3.9600.16348, for Windows 10 - 10.10240.16384) gets an error on the installation (gets to 97% and stalls, Error 0x800f0922). There is an error log file, but I am not sure what to look for. There is something there about a registry key error - is this the problem? Is there a later package for WMC I should use instead? Is there anyway to clean up the system and try again? Several attempts to uninstall and reinstall haven't helped. I did exactly the same thing on my test system (Dell 630) and it worked smoothly. Am I doing something wrong? Should I reformat and try again? Thanks
