found this article when searching for methods of solving the directx requirements for construct classic.
maybe its possible to include a minimum version of the construct required directx files with a silent install. (Small Installation Packages, Launch setup in silent mode)
there are games that have included the required .dlls only in their install, but that is some sort of a more risky way legally from what ive read. although this would be the most effective i guess.
as ive seen that many people are developing high quality games with cc and thinking of distributing, i would like to suggest that we would find a way to include a silent minimum install package in either the exporter or a streamlined way to integrate it afterwards.
what are the exact required files to make games run on an outdated machine, which directx update is the minimum which have to be included with a silent install ? so the filesize and the os and driver requirements can remain as small as possible.
an internet link is not a solution for distributed games imo.
