I am the Malwarebytes customer who encountered this problem. What do you need me to submit. I can tell you that when I run the standard routines from the DecisionModels app I get this message every time, pertaining to the VBA dll. I'm using Malwarebytes version 4.5.13.208, Update package version 1.05.59117 and component package version 1.0.1740. My account is current and is under jjoyner@integravc.com. I have logged the app folder (C:\Program Files (x86)\FastExcelv4\ and the *.xlam files in the Allow List. I've had similar problems with Malwarebytes when using Excel add-ins.
