"Error writing to find file: C:\Program Files\Common Files\Apple\Apple Application Support\pthreadVC2.dll. Verify that you have access to that directory."
That's consistent with disk/file damage. Try running a chkdsk over your C drive. There's instructions and a guided help in the following Microsoft document:

Does the chkdsk find/repair any damage? If so, does iTunes install properly afterwards?
