Help!!!

[test34]

By accident i deleted directx folder from regedit because someone told me to do so to fix the problem with my directx. I ran windows 7 ultimate and now i cannot install any of the directx required for the black ops. I try install dxwebsetup.exe it comes up with this error "An internal system error occured. Please refer to DXError.log and DirectX.log in your Windows folder to determine the problem". The same message comes up with all the directx updates that i download. If you know how to fix this pls tell me what to do.

DirectX.log Rapid

DXerror.log
