Hello Peter,
can you please screenshot this pop up?
Also, please check the default app setting in Menu>Tools>Settings>General>General section. Is the ‘Make default’ button greyed out?
Hello,
can you check what version of eM Client are you currently running?
We have not encountered this issue before, so it would greatly help us in determining the cause of it.
The full number can be found in Help>About section.
Hello,
I consulted the issue and this popup appears when eM Client can’t access the information about the default program.
Do you perhaps use any security software that could limit eM Client in this way?
Either way, this is a stand-alone issue, since this would only happen when you try to open Settings.
