Having problem installing the Flash player again

Somehow you have to go over this again on each new release

This time Flash 10, I cannot locate the msi as I did with Flash 9. I finally get it worked with the Adobe's Knowledge Base:

http://kb.adobe.com/selfservice/viewContent.do?externalId=fb1634cb&sliceId=1

It said the problem related to "incorrect permissions in the registry"

The procedure require SubInACL from Windows Resource Kit, onec it is installed make sure you add "C:\Program Files\Windows Resource Kits\Tools\" to PATH; otherwise, the script will not run effectively

I hope this fix the problem once for all

Flash "Unable to authenticate installer"

Having problem installing the Flash?

A lot of people do see Adobe's support forum
Adobe said try this http://www.adobe.com/support/flashplayer
For some people, it may due to incorrect permissions in the registry, as here

It does not work for me! if you did try everything else, here is the one that worked for me - Download the IE plugin directly from here instead of install it over the internet:
