I've installed QuickTime and the Matrox VFW codecs.
When I attempt to open LW, the progress bar loads and then it hangs. It does the same thing when I right click and try to "Run as administrator".
What could be causing this? Could it be that I'm running the 64 bit version of Win 8? Is it my integrated Intel graphics? Is it necessary to have a GFX chip that supports DirectX 11 (mine only supports DirectX 10.1)?
Considering that they haven't even begun to think about Lightworks under Win8 it is a poor place to start. Also considering that this Win8 is a developer preview and not a real release it is a bad place to start because a lot of things will be changed between now and Release To Manufacturers (RTM), I would expect significant changes between now and public Beta which is supposed to be early 2012.
I suggest booting into Win7 64 bit Home Premium or Pro and testing. As far as the internal Intel graphics, LW should run but it really works better with nVidia or ATI cards.
