CS3 - Still getting Activation Error Message with new Installer

[joshuas31889078]

I am in the middle of this same issue (I think).

Trying to install CS3 Design Suite on a old laptop running Windows 8.1. When I plug in the NEW serial number generated by Adobe Support, I get the red X instead of a green checkmark.  I don't know what I'm doing wrong here, I've reinstalled (from the new download links) three times already, and tried to follow the instructions on all of these forums.  Tried to remove the cache file and reinstall, and it still doesn't accept the new serial number.

When I choose the trial version, it counts down from thirty days.  I don't understand why the serial number provided by Adobe is not working?

Ok, thank you... I will try this right now

Well, now it looks like I can no longer uninstall CS3.  I'm now getting a message that says "The Installer Database is corrupt. Please contact Adobe Customer Service if this problem continues."  This is the first time I am seeing this message.  I will try using the Creative Cloud Cleaner Tool.  This is a huge concern.....
