Unable to send picture to eMclient

When we send a picture to eMclient, it resizes the picture (which is desirable) and tries to open eMclient. Then it gives an error message that eMclient has not been selected in default programs.

In the past support team of eMclient had suggested turning on Net 2.5 & 3.0 in control panel -> programs -> Turning windows features on/off. But now, this does not help. I even checked in default programs and eMclient is alread the default program.

Would be very thankful for your help.

Same problem here:

Hello,
please go to C:\Windows\System32 and open properties of mapi32.dll
Take a screenshot of the 'Details tab, please.

Also check if eM Client has all the protocols set in Control panels>Default programs.
