    Also, uninstalling .NET 3.5  and then installing 3.5 sp1 will also get you past this.

    Open your registry editor (Run > regedit). Go to: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > FileSystem:
  • NtfsDisable8dot3NameCreation must be: 0
  • Win31FileSystem must be: 0 (You can change it back, after installation.)

    I fixed this by adding the registry key (DWORD): HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftWindowsInstallerEnableAdminTSRemote with Value 1 msdn.microsoft.com/.../aa368353(v=vs.85).aspx
