default mail handler / mouse right-click context not working

Initiating an email attachment from a document on the desktop is not working.  “Mouse right-click > send to > mail recipient” generates an error popup “there is no email program associated to perform the requested action.  Please install…”

eM Client is registered as the default app.  I am using Windows 10 Pro 64-bit as in the attached screen shot.

Confirmed here.


To resolve this issue, go to Control Panel in Windows, navigate to “Programs and Features” - Turn Windows features On or Off and enable .NET framework 3.5.

It was already enabled.  For good measure I turned on the subfeatures as well and rebooted.  No effect.

Sorry to hear that, in that case contact me at and we will try and assist you further with this issue.

I have exact same issue as well. Same software. I even tinkered with my registry to add DLLPath c:\program Files (x86)\eM Client\MailCient.Mapi.dll. Should I delete the other email client entries?
