I have researched this problem and found the remedy to make the browser and mail programs the defaults in the Control Panel>Default Programs.
I have Windows 7 Professional and Windows Live Mail. I also went to the Options windows of Windows Live Mail to insure that it was set as the default. I then went to the Internet Explorer Internet Options window and found that "Internet Explorer (64-bit) cannot be the default browser."
I know about using IE 32-bit - I have had to use it for some websites.
What is the point of have 64-bit if it isn't usable in all situations?? I haven't noticed any difference between the 64-bit version and the 32-bit version. What is it??
I guess I need to figure out how to have my internet connection icon open the 32-bit version instead of the 64-bit version.
