First, I check the anti-virus settings and try to add a few exceptions. As in other matters, and to double-check the registry for errors. If this fails, only then I will engage in any kind of reinstallation. All to remove and install you can always have time again, but if you do not understand what it was, it would not be beneficial. Tips regarding the error code I esteemed, I have about them a few suspicions, I hope they do not come true.
