Attachment from Adobe Reader


I can't add file as attachment from Adobe Reader by the mail icon on bar. Adobe Reader shows that MS Outlook is default email program.
I have win10x64 and GW 2014r2 client.

Any ideas? GW is set as default mail client.

It is working on win7x86 with GW2014r2 and on win10x64 with GW7 client.

Edit: A little mistake in title: I meant GW2014 :)
