Downloaded and just as it was about to Run, it disappeared.
OK. I need to be very clear about this.
ALL that you will be doing with Internet Explorer is the RIGHT CLICK and "Save target as"... DO NOT let Internet Explorer do ANYTHING ELSE, OK?
Right click and "Save target as"
A Save dialog box will open.
Save the file to your downloads folder.
Here's where Internet Explorer is done. NOTHING MORE is needed out of it.
If you see this:
CLOSE IT using the "X". DO NOT (under ANY circumstances), click ANY of the buttons.
If you disregarded that last step, and end up with THIS:
Close the window - DO NOT (under ANY circumstances), click "Run".
Close Internet Explorer COMPLETELY.
Once Internet Explorer is CLOSED... Go to your Downloads folder and you'll find the installer.
RIGHT CLICK it and "Run As Administrator". It will open and you can install Flash Player.
Note: With the FULL installer, the downloaded file DOES NOT DELETE. You will have to do that manually once it's finished.
Thank you – downloaded and works fine.
You need to watch IE, and letting it do things for you. It'll cause more problems than it'll solve most of the time.
