I'm running Win 7 (64-bit), IE 10 and the latest Flash player (11.7.700.224). When trying to download purchased software from within my account (and another section as well) I get an error page telling me "Your browser (Internet Explorer 4 or earlier) is not supported by macromedia.com." This error page provides the following link. http://helpx.adobe.com/x-productkb/global/website-system-requirements.html I have reviewed the info on this page and verified all settings are correct in my browser and still no luck. I can access everything just fine using Chrome.
This is a known problem with IE10 on the Adobe website; I don't know if they are ever going to fix it.
The only circumvention is to user a different browser.
