Hello friends, just recently I have uploaded the MS Office 2010 software on my computer system that was previously having Office 2007 on it. All the applications are running fine and i don have any complains about it. It was just yesterday that when I made an Excel document and after completing it when I decided to save that document, i got this error saying " cannot save file is currently in use". Although I dont have any files open and even if use different names then also I get the same problem. Can any one help me to know what this whole problem and what can be done to overcome this problem.
