What does "No External Interface" mean?

[SAB041950]

Adobe Flash Player will not install the complete program.  It's telling me that it can only install a single file at a time.  The display box states that I have version 9.0.45.0 installed and my operating system is Windows XP then for the browser in states No External Interface.  Not sure how to correct the problem but it's telling me that Flash Player didn't install completely.
