Hi traumaticholler, thank you for your reply.
On the 'UpdatePack7R2-21.7.14.exe' file, I drag my .ISO image onto it and it integrates itself.
I put .WA files in the same directory as .ISO and UpdatePack7R2-21.7.14.exe
How should I understand that? 'The addon will conflict with some Windows Updates (.NET 3.5 Family), so leave the addon's integration to the last.'
Should I download any patches from Windows Update (.NET 3.5 Family) first and integrate them into the iso image?
