To avoid this issue, uninstall ADMT 3.1 before you upgrade to Windows Server 2008 R2.
To work around this issue, if ADMT 3.1 is not uninstalled before the upgrade, type the following command at a command prompt, and then press ENTER to uninstall ADMT 3.1:
%windir%\system32\msiexec.exe /x {F24F5CFB-B3AA-4EBB-BA61-A916DBEE37D5} /norestart /qn /log %windir%\ADMT\Logs\admtmsiuninstall.log
If ADMT 3.1 is configured to use a local database instance, you can uninstall Microsoft SQL Server 2005 Express by using the
Add/Remove Programs item in Control Panel.
