I have Word 2008 installed on a Mac G4. Every time a new update comes out I gamely try to install it, and the installer searches through all of my disc partitions and tells me that the update cannot be installed on ANY of my discs. The 12.1.1 version is installed on a disc partition 76 GB in size with 46 GB free space, so free space does not seem to be a problem. My OS is Tiger Version 10.4.11, so that does not seem to be the problem. I also have a 3-user license and the others are installed on a G5 tower (which updates OK) and a G5 powerbook (also updates OK) so that it why I am suspicious that the problem could somehow be related to the problem computer being a G4. Still, G4s should work fine, shouldn't they.
Is the problem that I can only updatge first with version 12.1.2 (I cannot remember having seen a 12.1.2 updater available) and then with a 12.1.3 and so on???, up to 12.1,4 and then 12.1.5???
In that case the problem is the lack of availability of a 12.1.2 updater, because I have tried with the assumption I had to start with the lowest number superior to what I have and that doesn't seem to help.
