I can't download my old Adobe Photoshop CS4, "The Installer Database is corrupt"

[Colhyena]

I've recently bought a new laptop and I'm trying to install my Photoshop CS4 that I purchased years ago. 

I've tried both the Akamai Downloader and the files from here: Download CS4 products 

Both result in an error that says "The Installer Database is corrupt. Please contact Adobe Customer Service."

What can I do?  I spent money on this program and I have the serial number listed in my Adobe account.

Thank you.

You can download the trial version of the software thru the page linked below and then use your current serial number to activate it.

Be sure to follow the steps outlined in the Note: Very Important Instructions section on the download pages at this site and have cookies enabled in your browser or else the download will not work properly.

Thanks for the reply.

The files to download on that page appear to be the same exact files that I found on this page here: Download CS4 products 

So it still didn't work.  Same error (this error occurs when I attempt to run the Setup.exe.

Did a little more digging.  I had to delete this file: Program Files\Common Files\Adobe\backup\caps.db

and then the setup.exe started working.
