Hi, it gets part way through installing and then says I need to download something extra to make it work (a DLL?), but my computer isn't connected to the internet. Does anyone know what to download to make it work, or is there an older version I can install that's compatible with Windows 09? Thanks, firstname.lastname@example.org
You couldn't have gotten an installer from this site/project. The original MPC is here and it's just an executable that you download and run.
If you're actually talking about MPC Home Cinema, it's site is over here: http://mpc-hc.sourceforge.net/
If you're installing some sort of codec pack with MPC something or other included, you need to check with that site. There are no codec packs here.
