Fix for Windows 10 Fall Creators Update


In October 2017 Microsoft began rolling out Windows 10 Fall Creators update, release 1709. As with any update, there were some problems and some unintended consequences. One change was how the Windows memory manager worked, which caused a problem for ExtendSim such that it could hang up or crash on launch. 

To resolve the conflict with Windows 10 Fall Creators update either:

Download a replacement DLL. You will copy the DLL into the folder "Program Files (x86)/ExtendSim" where it will replace the existing "asimagin.dll".

Or, if you are using ExtendSim 9, download the above revised ExtendSim 9.2 Updater which now includes the updated DLL.

This affects ExtendSim 7.0 to 9.2 released prior to November 16, 2017.
