topic #60125-- 1900 Updater 1.1

Checking this forum, it looks like this topic has come up before: the PMDG 1900 updater is run on a current install, but aborts because it cannot locate the installation. I just purchased the 1900 and have it installed twice on a single physical drive: the Windows volume (defaults), and a dedicated FS2004 volume. I have run the updater 1.1 from both volumes, from the same folder as FS2004, even from the 1900 folder, right next to the aircraft.cfg file... and the updater sees nothing. Does the updater need to be placed somewhere specific? Do folder names and paths have to be just so? What conditions have to be satisfied to make this .exe function?
