Yeah ive had a look,But its hard to find out what it means...with all those things in the error writingHave you tried searching google for the file, to see what it is?
Any actual problems with the computer besides that error messege? Is the error affecting anything?
that error looks like it is referring to a file path that is no longer valid. In particular it is coming from the D drive which is probably an optical drive on your system (assumption on my part). It is also referring to something you are or were installing in the Programs directory. My guess is you installed or uninstalled something recently and windows choked on it in the end of the process and a reboot fixed the problem.
This is kind of normal behavior for windows at times.
