DLL resolving the conflict with Windows 10 Fall Creators Update

If you are running any version of ExtendSim released prior to November 15, 2017, you will need to replace a DLL within ExtendSim to enable it to run on Windows 10 Fall Creators Update.

Download this DLL

Download and Save the "ExtendSim-Win10FCUfix.zip" file, then decompress it to reveal "asimagin.dll". Copy this DLL into the folder "Program Files (x86)/ExtendSim" where it will replace the existing "asimagin.dll". Note: If you don't get a message that it's replacing the DLL, you're in the wrong folder. Then, restart ExtendSim.

Get the ExtendSim 9.3 Updater

If you are using ExtendSim 9, you may choose to download and run a revised 9.3 updater which includes the replacement DLL.
