I did, just today while trying to load up some topos onto my 30x for turkey hunting this coming weekend. I chose option B for working around the problem, however there was no entry for uninstalling just MapInstall from my W10 workstation. I just renamed the folder & ran the installer for v4.0.4 and it's happily transferring the maps now.
