Error reading file

Hi,

We are using eDrawing viewer 2013, from a server, hosting citrix sessions.

We keep getting errors when opening .easm files that have recently been created.  They open fine in eDrawing viewer 2017.

I can't simply upgrade the 2013 version to 2017 (I can in a couple of months when the new server builds happen).

Is there a way I can convert the 2017 files to open in 2013 version?

Thanks in advance.
