A couple users recently reported issues with Internet Explorer and the new Microsoft Edge browser claiming that "The signature of EpicTable-220.127.116.11.exe is corrupt or invalid." It's neither. It is, however, signed with a hash algorithm that Microsoft browsers no longer like. If you right-click on the file in Explorer (not to be confused with IE or Internet Explorer) and select Properties and then Digital Signatures, you can see that Windows says it's a valid signature. IE and Edge don't like it. Chrome is fine with it. It's also the case that despite the browsers' complaint, the file downloads just fine, and you can go to your Downloads file and double-click on it to run it, and life is good. Meanwhile, I'm going to go figure out how to make my not-so-cheap signing certificate with a year left before its expiration more palatable to the Microsoft browsers.
A big thanks to the people who reported this to me.
