After the successful installation of the latest update of Adobe Acrobat Reader DC 2019.008.20074, in an attempt to attach the pdf opened at that time, it no longer opens the Windows Live Mail application but now opens Outlook.
I state that Windows Live Mail is the application that has been set as default in the operating system (Windows 10 in this case) for emails. The association with files of type ".eml" is associated with Windows Live Mail. The "mailto:" protocol is associated with Windows Live Mail.
Would it be possible to set up Windows Live Mail again? Maybe also acting on the Windows registry?
In Reader, try Edit>Preferences>Email accounts. You should be able to set it from there.
I tried this. I was able to set the default up as directed, went back in to retry and received the same error. (When I look to see, it still shows: default email application (unknown)). So, the "unknown" has to indicate that my default email is still not set up when I see that in the email account, under preferences, shows my email ! Ugh!!!
adobe is opening all my email files and this is not acceptable use of this application. how do I sstop this ?????
Adobe is a company. What Adobe application are you referring to? What's your OS version?
What do you mean by "email files"?
