Hi 1a2b3cboo,
Please use the offline installer posted at the bottom of the Installation problems | Flash Player | Mac page in the 'Still having problems' section.
Per the folks who handle the online installer it is not compatible with OS X 10.6. The download pages performs browser/os detection to determine which installer to offer. On a 10.6 system it should have downloaded the offline installer, instead of the online installer. As such I'd like to get some more info from you on this. Did you download this file using the 10.6 machine, or some other system? Did you download it from adobe.com or some other location? What is the exact URL for the page you downloaded this installer from?
Thank you in advance.

Thanks, I tried the suggested offline installer from your link which worked and shows up as 17.0.0.188 in system preferences.
I got the installer on this machine with 10.6, but I never downloaded this manually from Adobe. An Adobe pop-up apeared when I was using the browser to view some flash content (TV network), telling me that a new version was available. I have set up the Flash preferences to allow automatic updates, but it somehow always seems to suggest me to do it through this pop-up window instead.
I seem to remember that the automatic update is delayed a few days, so I usually go for the install button on the pop-up.
