Ever annoying VBA password prompt at close of excel.

As many users have listed on the Internet. I am also getting the pop-up asking for VBA password when closing excel.

I have my code deployed on approximately 50 laptops. Various manufacturers of laptops and versions of Windows ranging from Windows XP to Windows 10. All running Office 2010 or 2013. Only 4 machines have the popup error. I thought the problem was related to the last Microsoft update but does not appear to be the case. Has anyone come up with a solution or is it just trial an error? Seems to be related to forms. I can open a file have it load a file and then auto open a form, close it and save the file and the error will appear. Very repeatable on 4 machines but not on any other.

The following are a couple well written links relating to problem

Below is what I have for add-ins. They are all inactive or do they need to be totally removed from computer?

Anyone with ideas?

I have attached sample file. Password for VBA is test
Very repeatable error on my computer. Open the file it auto opens a splash screen and then checks to see if pivot-table is loaded or not and then selects Order tab.
Then click X and then when requested save document.
