Unable to get my software opened
I am a new computer user. I need some help for my recent problem. I want to open my installed software but it can not be opened. I had tried to open from desktop shortcuts than it shows a open with window. I tried from start menu, same problem occurs there also. It also says rundll32.exe file missing. I can not figure what the problem is.
Please give me the idea about the problem as well as the solution of the problem.
