Excellent news that MTU is working some magic to defeat the 1004 error. I look forward to trying it when it is released.
I also tried out the Belarc Advisory and it showed everything as it should be, but with 1 missing critical update for Outlook. This updated could have come out after I did the SP3 etc. updates. The fun begins when I went to get that 1 Outlook update and Microspft told me SP3 was not installed. Now, it was recently installed and everything, including the Belarc Advisory said it was installed. So... I reinstalled it, followed by 2 rounds of additional patches, until at last Miscrosoft said that all possible patches (including custom) were installed, Again.
I tried Hoster 4.01 and the 1004 error is still there. Tonight I will go to Windows Update and see if it wants to install SP3 a 3rd time
