let me see if I understood, I just install windows and drivers, road runner, flash player 10, frame net 3.5, then your plugins ...
may be that when you install everything, before your plugins, these dlls is installed, wininet.dll and urlmon.dll .... so your plugins not installed because it is already installed on the machine?
I thought your plugin needed to make some modification to these dlls to work or something? let me if I understood, then you need these dlls, if they are already installed on the machine? that you mean? , so , if i put ignoted with both dlls , your plugins working fine ? ..
maybe any driver or another application need that dlls too ?
so what do you think so then stop, or try to installed only windows without drivers, road runner, and your plugins and see if installed everything perfect?
