Problem Installing Adobe Flex Builder 3 (Standalone)

Question

I have attempted a few times today to install the Flex Builder 3 standalone file, but I am having issues. I am currently using Adobe CS4 Design Premium on my computer.
I am new to this type of application development.  Currently, I mainly used flash to create my interactive applications, but I need to branch out to create more complex applications.  As I already know actionscript 3.0, I was interesting into getting into Flex.  I do not know Javascript, C++, etc.
Once I download the standalone file to my desktop and run the installer, I do not choose to download Flash Player 9 because I already have nor do I choose do download the Coldfusion or JSEclipse Plug-in as I do not have Eclipse on my computer (it comes with the standalone as I have been led to believe).  After running the installer, it almost gets to the end and then I get the following error message:
I click OK, it finishes the install and says
I go to the log file and get the following:

Can anybody help me on this?  Is there something I missing prior to download?

We're in the same boat here - the the behavour of xsd:all in
BETA 3 renders our Flex app virtually useless because of
communication issues with the backend webservice. We have studied
the proposed workaround suggested, unfortunately we only control
the FLEX app - we do not control the WS we have to integrate with.
As a result we've gone back to BETA 2 to do some critical
changes in the software but the "Beta expired." message we've been
receiving is really not well received. As we have been very
proactive in supporting development in the BETA phases including
reporitng bugs, we think that Adobe shoudl also have some
flexibility here and offer ways to extend the BETA 2. We're not
asking for any type of support during that phase - purely the
ability to compile our source until we can implement the full work
around which will allow the software to run on BETA 3. The
suggestion to change dates or go to previous restore points do not
work well here with our numerous developers.
