I have installed the latest version of Flash using the installer on the Adobe website and no errors occur during installation. However, when installation is complete, I still can't use websites that require Flash (I am prompted to go install Flash). Even the troubleshooter on the Adobe site says that I don't have Flash installed when I check it in the first step. I am running Windows 7 (64-bit) and Internet Explorer 11 (I downloaded and tried Firefox and got the same results). Please help. Thanks.
