Yes it is. That's what makes it so frustrating. Everything seems to be there, but it just won't open Mailto giving me that angering message that no default is set if eM Client is not installed. I even used the same TB 68 settings as my old PC that I sold to a friend has (It's still set up with my email address) except for using Newsgroup as the Server Type. I have POP Mail Server as the Server Type on this PC.

Could that be the reason I'm having a problem? This is one of the weirdest issues I've ever had on a PC.

I notice that the name in the registry says Thunderbird and not Mozilla Thunderbird as the Value Name under the path Computer\HKEY_LOCAL_MACHINE\SOFTWARE\RegisteredApplications

Wow! I just did a search using the program Everything. I set the search on Everything and searched eM Client. It displayed hundreds of entries. I then searched Mozilla Thunderbird with the same search setting and it displays only 8 entries, three of which are shortcuts!! I then searched just Thunderbird and it displays 39 entries which includes twelve .exe setup files and a few shortcuts.

It also gives yet another example of what registry keys are needed to register for mailto. ... windows-10

I found those entries.

These are some other registry entries for eM Client and TB. I'm hoping that this will shed light on the fixing the issue of Send to on my PC not opening in TB but opening with eM Client.

This one is for eM Client

This one is for TB
