Can't get my Adobe creative suite 4 web premium to reinstall after a HD crash. Need help!

After moving over a number of years to three different cities, I could not find the product key for my copy of Adobe Creative Suite 4, Web Premium. Yesterday that was resolved and I have my product code back. However, when I try to install the package, first the install program asks which programs to install. When I then let it go further, it starts looking into the environment before actually installing. However, every time it finishes the check, consistently an error window comes up that says:

    Critical errors were found in Setup.

    Please see the Setup. log file for details.

I have a desktop .jpg file on this.

Setup log file?? Can't find such a file. Can't therefore find what the problem is. I have even gone into Uninstall or change a program to uninstall any programs I know are in the package (... without uninstalling other Adobe programs ....). It cleaned out some of them but refused to uninstall "Adobe Creative Suite 4 Web Premium".

I have been through customer service 3 times and told to go to the forums. I would love to get the entire suite working but especially need Dreamweaver working to continue development of a website I have been developing for over 16 years (see woodsoftheworld.org. Reports over 15,200 different woods ).

The original installation was lost when the HD it was on went totally dead(!). P.S.- I have been a power user on personal computers since prior to Apple 1.

I am in Brockville area, Ontario Canada. Sure hope someone can solve this for me.
