[Tiny Mud]

Haven't used MeGUI for a few weeks but when I did MeGUI 2818 Developer crashed upon opening and I was greeted with this error:

MeGUI encountered a fatal error and may not be able to proceed. Reason: Object reference not set to an instance of an object.

I checked Event Viewer/Windows Logs/Application and noticed that the crash was a conflict between MeGUI and .NET Framework 4.7.1.
I had resonantly installed a .NET Framework 4.7.1 update KB4054852 through Windows Update.

I uninstalled the KB4054852 update and MeGUI worked fine.

I've used MeGUI Developer for years and love it - This is my 1st real issue with it.

Win7 Ultimate 64-bit

Looks an issue with MeGUI not handling this .NET Framework 4.7.1 update.

Thanks for any info - RON

--------------------------------------
Update: After uninstalling the .NET Framework 4.7.1 update KB4054852, I updated MeGUI to v2827 developer then downloaded
NDP471-KB4054856-x86-x64-AllOS.exe and installed it manually and all is well.

My only guess is that MeGUI v2818 becomes dead in the water if you install the .NET Framework 4.7.1 update KB4054852 before updating
MeGUI to v2827.

So the lessen learned is to update Megui to the latest version before updating .NET Framework ;o)
