There is no such requirement of adming rights to view flash files, it is may be due to your preference setting of you PC.
Do you know what preferences I may need to change please? - I ideally don't want to set 55 new pc's up and give 55 users domain admin rights
You may post your query in the forum Flash player.
Does the same thing happen on the computer where you originally installed Flash Player?
What do you see as a standard domain user: just a blank screen, or an error message?
Can you see the Flash animation at http://www.adobe.com/software/flash/about/ ?
When you log into the user I originally installed flash on, it works without any problems. It's when you log into another user (thats not a domain administrator) that the problems arise.
You can see in the control panel that flash is installed, but when you try to view any flash content (like the link you posted) it says that flash player is not installed, click this link to install it (which takes you to get.adobe.com/flashplayer).
It might be a permission problem in the Flash Player install folder. Try a clean install on the original machine.
If that does not resolve your problem, can you tell what Windows version & edition you are using?
Also check the permissions of all files in
