What do I do when I receive error 75 when trying to update my software?

See this Apple article: If you see an error when you update or restore your iPhone, iPad, or iPod

Hey, I am facing the same problem but in different situation. Actually I faced this error while using one of mine apps. So, I want to ask that how can I get rid of this problem permanently?

Regards.
