Did you get any sort of reply to this?
Did you ever resolve the issue?
Obviously I didn't get a reply here, but I called Adobe and got excellent help. What happened is that the installer does what I would call a system check and then asks you if you want to proceed with the installation. Some of the responses that I got from the "system check" sounded less than positive, but I assumed that since the installer was giving me the option to proceed, that I could deal with these later. This turned out to be a big mistake. The lesson learned is that if you get any messages that seem like they might be errors, cancel the installation and address the issues they reflect. I also had trouble identifying the apache files that cf 10 needed to know about so I had a hard time linking cf with apache, but a guy in my office was more experienced with apache and was able to straighten me out.
