I am trying to install media centre on windows 8. I downloaded a key and installed it on my laptop with no problems.

When I try to install on it my desktop it informs me that the key checks out but then hits me with an error saying 'Something went wrong', 'Close this wizard and try again'.

After numerous reboots it always throws the same error.

Anybody have any idea why?

is it the same key? – Louis Oct 30 '12 at 10:12
@Louis - No, different key – John Oct 30 '12 at 10:19
If you paste this into Explorer a log file will open in a text editor: %localappdata%\microsoft\windows\Windows Anytime Upgrade\Upgrade.log. Can you post the part of that was written during the error? – Louis Oct 30 '12 at 10:41
Have you tried Right Click "Run as Administrator"? – Vian Esterhuizen Oct 30 '12 at 14:05
@vian-esterhuizen - no. this option is not available – John Oct 31 '12 at 6:04
  1. Make sure everything is updated in Windows Update
  2. If you have a file called "ehome" in "c:\windows", delete/move it.
  3. If you have moved your "Users" folder to another disk (e.g. D:\Users) with a junction point, put it back first.

everything is up to date, there is no ehome file in C:\windows and I have not moved the Users folder anywhere. Also, out of curiosity, what is a junction point? – John Oct 30 '12 at 22:40
A junction point is like an alias for one directory to another location. Apparently the installer doesn't like it. I had exactly the same issue and #2 was problem. Do you have an error in the file \Users\<username>\AppData\Local\Microsoft\Windows\Windows Anytime Upgrade\Upgrade.log ? – cdm9002 Oct 31 '12 at 1:23
yes. it is in the edit. – John Oct 31 '12 at 6:05

If you have a Junction Point the solution for the Media Center Pack installation's problem is simple (DO NOT COPY again the Users directory back to system partition but) follow these simple steps:

  • Launch REGEDIT (Windows+R, then type Regedit)

  • Searching "ProfileList" in Keys and Values, it goes to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList"

  • Change %SystemDrive% with the unit that contains your Users folder in Default, ProfilesDirectory and Public (LEAVE ProgramData AS IS) for example: %SystemDrive%\Users --> D:\Users

  • Start again Media Center Pack installation, it will work!
  • After machine restarting, you can put %SystemDrive% variable again inside the ProfileList Key Hoping to help for this problem. Best Regards!
