EXACTLY, for a looooong time now Yumeyao and myself have been using a "stubbed" mrt. in order to save file space we use a small exe that will initiate a web browser to open to download the MRT files however the version info is in the stub and the correct reg key is placed in the registry. the 2 latter functions make MU happy. check the mrt.exe in the update pack. here is a link to an original thread at RyanVM from 2007 http://www.ryanvm.net/forum/viewtopic.php?t=4852&highlight=mrt+stub
