Windows 7 error code

I come with two problems now. To start, I've recently got windows 7 x64 (not original, cracked). When I try to install this I get this message; Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code 0x8007001 At the moment I got Windows XP x32. The second problem is not related to this, but I thought it would be much simpler to combine this two in one topic. I've got a nVidia GeForce 6600 GT graphics card, and DirectX 9.0c(4.09.0000.0904) installed at the moment, but for some reason this comes up when I try to run the game Heroes of Newerth; Ghost::Init() - D3D_SelectMaterial: problem with NULL shader: g_iCurrentVertexShader invalid, g_iCurrentPixelShader invalid. Thanks on ahead! /gavexor Edit: Just realized I've got another problem, neither this connected to the first one. My sound refuse to work, even though it's up to date
