Crash every time em Client displays a file list


Thanks for a great mail client, which has worked well for some years.
However it now crashes each time a windows file list is displayed, for example when you choose insert file, (or when you click the ellipsis alongside the database location in settings).

2 events are created, the first is from .NET Runtime and the second from MailClient.exe as below

Application: MailClient.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

Any help would be wonderful. Thanks in advance


Hi Alastair, if the application crashes, is there an crash report window displayed? If so, can you please click on the “Show error” button, copy the content of the crash log and submit it to us here on the forum for more information about the issue?

Thank you,

Unfortunately emClient just dies and windows shows the application failed error… and I cant find anything in the appdata logs directory  

I am having the exact same error when trying to attach, save attachments, insert, etc.  ~mike 

Please try to update your .NET framework to the latest release (4.5.2) and update your eM Client to this release, and please check if the issue persists.
