I guess that your msiserver.reg file have some problem with it. The directory of the msiserver.reg file/folder in the registry that got wreck someway was below the position HKEY_lOCAL_MACHINE/SYSTEM/present Control Set/services/msiserver, for a number of reason I had a file that appeared a bit like: MSiServer or something with strange capitalization. I check with 2 additional win 7 64 bit computers, one pro and an additional ult, like mine, and their's were both lower case. there was also no WOW64 file or a associate directory which mine had (bad). as a Microsoft sustain person I would suggest exporting together 32 and 64 bit copies of this folder in the directory to the internet someplace so that natives can download it and observe if they have the similar difficulty and are not as lucky as I am to have multiple computers in that I can access.
