CS5 Master Collection - launcher failed??

Question

Anyone have an idea why the trial launcher for CS5 MC fails to initialize? File not found? The log file shows this...

I don't get it - anyone can help?
Thanks.

Hi David - tried a reply to your email but it came back as undeliverable to the reply email address.
Thanks for taking the time to try and help. I didn't find a lot on the web with regards to this product. I don't think it's a corrupt file as the same trial files installed on other systems just fine. More on that below.
I did find a support article on Adobe discussing bootstrapper failed launches but it didn't provide any specific info. Just said bootstrapper looked for certain conditions/files on the system when launching but not what conditions etc. It said to run the CS5 cleaner but it doesn't find anything on the system because CS5 hasn't even been installed. Doesn't get that far. Install/launcher fails right after running setup. The Adobe Support Advisor app doesn't find anything either when I ran it even though the error message instructs me to run it to see what is wrong. I'm running a WinXP Pro SP3 32bit system, 4gb mem, and 500gb HD, 9800GT Nvidia etc etc.
I tried installing the CS5 trial on two different systems though at a friend's place. One was a Win7 x64 and the other a WinXP 32bit Home Edition. It  lauched and installed fine on both those systems. I had another friend install this same windows trial CS5 version on his MAC even and that went fine. In all cases this is the same CS5 trial files I can't seem to initiate on my system.
I tried turning off the firewall, antivirus and any other malware app/protection running. Nothing. Tried an install in safe mode - nothing. I even ran CS3 and CS4 cleaners just to see what they turned up which was nothing. I also tried turning off all background services using the msconfig method described on the forum here.
Honestly I have no clue what to do at this point. I figure I'm going to have to do a clean install of the OS on a hard drive and try installing the trial CS5 then and see what happens.
Thanks again for helping!
