Is Eudora 8.0.0.9 compatible with Windows 10? Is it possible that Eudora 7 will work with Windows 10?
No, the software is not compatible with Windows 10 because it's a very old application. I don't recommend using such old applications with emails, and especially with data from emails. Try using Mozilla Thunderbird, Outlook or PostBox.
I have been using EUDORA 7.1.0.9 for about a year running windows 10 with no problem.
