Can't reinstall TCS1 on WIN7- need help

I had previously installed TCS1 on my Win7 64-bit system almost a year ago. It had worked fine on WIN7 until recently, Captivate was doing some odd things and began shutting itself down (i.e. when importing slides, working with PS, etc.). So I decided to uninstall the entire suite and reinstall....hoping that will fix multiple minor oddities.

However, now when I try to re-install, it goes through the "System Check" and gives me the message below and won't allow me to install. Has anyone experienced this and is there any ideas on how to fix this or get around it?

Note: I've been trying to contact Adobe Tech support...was in the queue for 50 mins and when I finally got someone to talk to (less then 1 min) the line dropped. I called back in and am in the queue again and it's been 35mins.... 😞

Thanks ahead for any suggestions or fixes you can provide.
