Adobe Flash Player Installation Problem

When I try and download Adobe Flash Player, the download program tells me that my "security settings don't allow the program to be downloaded."

This has never happened before.  Normally, I just make sure that the checkmarks on the Google toolbar/Chrome are not checked, hit install and it does it.  (Of course, it does ask me if Flash Player can make changes to the program, and I follow the instructions that then "run" the program and installs it).

Another issue, I don't know if this is an issue with NIS security settings - if it is I have no idea where to check and change a setting.  Could be a Window security issue, but again, I don't have much experience with that kind of stuff.  I've looked at the Windows/tools settings but I'm drawing a blank.  If someone could help me, I would appreciate it.

Regards,
