As a recap, Adobe Flash does not work properly in any 64-bit web browser. All popular browsers are available in 64-bit versions, but Internet Explorer is the only one that comes installed and activated by default in Windows 7. Many non-technical internet users don't understand that IE 64-bit cannot run Flash. The result is a lot of user disappointment and seemingly non-functioning websites.
The obvious solution is to switch to IE 32-bit and not use any 64-bit browsers... thus losing the blazing internet speed that we all would love to experience.
