eM Client Crashing Randomly

I just installed eM Client and got my exchange email going with it.  But it’s crashing repeatedly.  I have set the exchange server up like normal but I also have an alias on the account that I need to use.  I’m not sure if this has anything to do with the issue or not.  I’ve tried deleting the account completely and recreating as well as rebuilding the database using the database recovery tool you guys provide.  

Here’s my error log:

eM Client (6.0.20648.0)Windows: Microsoft Windows NT 6.1.7601 Service Pack 1, Framework: 4.0.30319.1022
The following error has occurred:
System.IO.FileNotFoundException: Could not load file or assembly ‘System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

A strange thing I’ve noticed is that if I leave the crash window open my eM Client continues to run just fine and send/receive emails.  But as soon as I close the crash report window it shuts eM Client down.  

Hi Chris, sorry for my belated reply, I’ve reported the issue to the developers and I’ll let you know once I get some information about the issue.

Sorry about the inconvenience,
Paul.

Hi again Chris, this issue seems to be related to your .NET framework installation, seems like you have .NET Framework Client Profile installed on your computer, which is a .NET installation without some important components.
Can you try to install .NET Framework version 4.5.3, that should resolve the issue.

Thank you,
Paul.

Updating my .Net to the current version fixed the issue for me.  Thank you!

Great, glad I could help, let us know if you come across any other issues or questions, we’ll be happy to help.

Thank you,
Paul.
