The problem with the update situation, it isn't affecting everyone, only isolated cases.  Could this be Internet Explorer 11 browser which cropped up earlier this year?  All my update installs work perfectly fine, however, this is within an older WinXP environment.  I will be migrating everything to a new PC system very soon and hope that I won't encounter any such issues.

As for morph packages, the uninstallers work perfectly fine if nothing has changed after the initial installations.  IIRC, even after moving files around, the uninstallers will run but will not flag any errors in finding files.  It just won't remove anything.  But if you re-install the packages, you must run the updater after each one individually,  Don't install all the morphs at once then run the updater.  There are existing issues that will occur.
