I'm try to figure find some documentation that confirms or denies, either online or printed. to back up my thought. for instance merge module DAO360 has dependency of MDAC 2.5 SP3 (English). do i include MDAC 2.5 SP3 and MDAC 2.8 in project. i believe i eliminate MDAC 2.5 SP3 from being included. since my projct includes over 25 merge modules. i wanted have it as bullet proof as possible. this installation project is gone out to 700 sites, windows 98 to Windows server 2003. any help will be appreciated
