I have tried to apply 10.1.2, 10.1.4, and 10.1.5 to my Office app. but all I get is a spinning beachball in InstallerVise. I haven't been dilligent in upgrading, and I wondered if I forgot something. I don't use it much at all, but I want to try to keep it up to date, especially if there are security issues. Thanks for any help.
