Windows Media Creation Tool: Fix Something Happened Error

This error can have several causes.

Please have a look at the following things:

• Make sure you have enough disk space available. If the download has already been canceled before, please delete the content from the folder C:\$Windows.~WS (also remove the content from the recycling bin).
• Ensure that if you are using a 64 bit version of Windows 7, you also have to use of the 64 bit version of the Media Creation Tool, otherwise the corresponding 32 bit version.
• Make sure that you are running the Media Creation Tool within an administrator account on Windows 7 or 8.1 - not under a normal user account. It is not sufficient to only run the tool as administrator.
• Even the old Windows 7 or 8.1 must be up to date. Install all updates that are available, the Creation Tool can also fail because your Windows is not up to date.
• The download can be faulty, if necessary, download it again.
• Virus scanners can interfere with the update process, disable or even uninstall them completely if necessary.
• Under certain circumstances your old version of Windows could be not activated properly. Since the update requires a proper activation, a new activation of the system can help.
• Open Regedit and go to the path "Computer > HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > WindowsUpdate > OSUpgrade". After that, right click in to this path and create a new value by selecting "New > DWORD (32-bit) value" from the context menu. Give it the name "AllowOSUpgrade" and the value 1 in the basis hexadecimal.

I think that if you are keeping all of this things in mind, you should be able to run your update.
