ITunes will not open, get error message 7(windows error 126) this application has failed to start because d3d9.dll was not found. re-installing the application may fix this problem. well i did and did not fix anything.

this application has failed to start because d3d8thk.dll could not be found. I looked that file up and it seems its part of directx. i installed directx again but that still did not help.

That one is a DirectX 8 module and might not be included in the most recent DirectX 9 redistributable available from Microsoft. If it's been installed as part of a partial DirectX 8 install (as part of a game for example), that can cause the issue. Can you track down a full DirectX 8 redistributable? If so, if you install that, does that clear up the iTunes error?
