What is the reason of runtime error (abnormal program termination) and how do you resolve it?

I installed Arcsoft photoimpression, and then when I am trying to lauch it, this message appears "runtime error. Abnormal program termination" I'm sure the software Arcsoft photoimpression has no problem because I have used it already before. I reformatted my pc so I reinstalled it.

So what's the reason of this error? And how to solve it?

Thank you.
Update: @Jacob - Thanks, but the registry cleaner you gave isn't free.

I need a free one. Thank you.
