Hi ,
Unfortunately we do not have any machines with McAfee installed, so I can’t do any testing for that. Did you confirm that you had temporarily disabled any firewall before downloading the dependencies?
We do not have the zip files available any longer. The current format for downloading the dependencies allows us to more reliably ensure that the correct dependencies are downloaded and installed for the version of the Engine that you are trying to build. The initial format of providing the dependencies in zip files was prone to errors where the wrong files were downloaded and used.
