Still Can't Upgrade

Question

I posted the following problem one week ago. I continue to receive update notifications for a 13.0.1 update for Illustrator, which continues to give the following error message when attempting an install: Adobe Illustrator CS3 13.0.1 Update failed to install. The update cannot be applied to the product. My daughter received the Updater message today for her copy of Illustrator running on her Intel-based MacBook Pro running Leopard 10.5.8, and she experienced the same failure to install, along with the same error message. What's going on with the 13.0.1 Illustrator updater?
Adobe Updater continually opens and attempts to update my copy of Illustrator with the 13.0.1 updater, but fails each time with a notification that the update cannot be applied to program installed. I have Illustrator 13.0.0 installed on a Mac G5 Dual Processor PPC running OS 10.5.8.
I have also downloaded the updater DMG and have received the same error message --- that it cannot update the installed program (Illustrator 13.0.0).

Well, if it were my system, the fix outlined below wouldn't have worked. Numerous requests for that fix can be found all over the Adobe Forum for Illustrator. The "truth" is that the Installers folder in the Adobe folder of the Application Support folder is not being well managed by the successive updates issued by Adobe. Only after I removed the garbage written into the Installers folder was I able to update Illustrator. That's not a consequence of my having a system problem, but rather the file management of the Patcher program. In any case, thanks to a Forum member, I was able to resolve the issue, and that's what matters most.
Go to MacHD/Library/Application Support/Adobe/Installers, locate the {C4519961-AC64-4565-B3AF-9050296B5D5A}.patch file and delete it.
