"Grant offline exception" Not Work? "Sign-in" dialog still prompts

Hello guys,

I want disable "Sign-in" dialog to avoid everyone needs to login with Adobe ID.

So I use "Grant offline Exception" function in Acrobat Customization Wizard.

And it's successful.

Then, I tried on Windows10 VM. Also "Sign-in" dialog didn't prompt. (it seems work.)

However, it DID NOT WORK on Windows 7 Host. "Sign-in" dialog prompts EVERY TIME when i open Acrobat

(I use Setup.exe to install)

MST is indeed in setup.ini

Thanks for help.

Fred
