Eusing Registry cleaner error shown

I have several registry cleaners in my computer which are CCleaner, RegScrubVista and Eusing. Two of them are working correctly except for Eusing which seems to bring up an error message whenever I open it. The error is shown below. I need someone to shed some light on how to solve this.
