I was able to install the update to patch the ADMT MSDE runtime and received no error messages. My process to install the update was as follows:
Stop the MSSQL$MS_ADMT service.
Make a backup of the %windir%\ADMT\MSSQL$MS_ADMT directory.
Run the KB948110 installer with the command line SQLWMSDE-KB948110-x86-ENU.exe /upgradesp sqlrun INSTANCENAME=MS_ADMT /l*v %windir%\WMSDE.log
Start the MSSQL$MS_ADMT service.
After doing that, Automatic Updates detected that the patch was installed and stopped asking to install it.
Cheers
