Sage 300 2016 upgrade

Dear Team, 

Currently i have my own custom applications from Macro Records, and I have problem when i do Sage upgrade to latest version of Sage 300 i need to open my cording program and re-add the DLL files of Accpac.Advavantage.dll, Is there any better way we can do without access to our cording program to change it ?

Please advise.

Regards,

Sakada
