Can't install Dreamweaver CS4 on WIndows 7. Setup error

Question

I can't install Dreamweaver CS4 on WIndows 7.  I get a vague error that says Setup error, sontact Adobe Customer Support. Adobe Customer Support refuses to help me.  That really upsets me. 

Answer 1

First of all I would like to thank the people that responded to my post.  I am extreemly impressed with your eagerness to help and your concern for my problem.  Thank you very much! I appreciate it.
I did not see a way to get a transcript of my chat.  I should have printed it at the conclusion of my chat. Overall though, I think my concerns are with Windows itself and also how Adobe as a company handles a call from someone who gets an installation error that says "call Adobe Customer Support". I purchased this program to run on Windows 7 and I am installing it on a Windows 7 computer. I feel that if Adobe is going to give a vague error message and tell you to contact them, they should give me more assistance than "your product is too old, good luck on the forums". I could see if I am calling and asking them how to do something, maybe my product is too old for that, but I think their responce was unacceptable.  I hope enough other people complain so that Adobe changes this policy.
Wow, this has taken an enormous amount of time to deal with. I imagine this is mainly a Windows file permissions issue, but I think Adobe needs to take some ownership for a client having to spend many HOURS trying to install their program on the original OS they purchased the program for.
I definitely do not like the way the Adobe Dreamweaver installer deals with errors. Here are the facts as I know them.
When the installer would fail on install, the subsequesnt install would fail, but it would give a VERY cryptic error stating that the install failed and I need to contact Adobe customer service.
In order to re-install I had to un-install.  Naturally my un-installs failed every time, too. After lots of trial and error and checking the forumns, I found   the program install folders under c:\programs. I deleted them, re-booted, unistalled again with no errors.  Then I could re-install without the vague "contact Adobe customer support" error.  Note that I had to re-install several times to get to the bottom of the installation problem so this took a long time to figure out.
In the end, I had to manually delete files from C:\Windows\Installer in order to get Dreamweaver to install.  This took a long time to figure out, too.  It still installed with errors, but it said Dreamweaver would work with limited functionality. So far this is good enough for me and I am tired of spending non-billable time on this.
Following is one of the main erros I got during the first failed install.  IF ANYONE KNOWS EXACTLY WHY MY INSTALL WAS FAILING I WOULD LIKE TO KNOW.  IT SEEMS LIKE IT DID NOT HAVE PERMISSION FROM THE OPERATING SYSTEM TO ACCESS THOSE FILES, BUT THAT SHOULD NOT BE POSSIBLE AS THE PROGRAM IS INSTALLED AS ADMINISTRATOR. Any thoughts???
Thanks again everyone who helped!
