Go to Computer, in the left pane click the arrow by your C;\ drive, Find Program files and Program Files(x86) and open each one in turn, find the Rising program folder and open it. If there is a file called Uninstall, try clicking that.
If you just delete the Rising files there will still be 100s or 1000s of registry entries left over.
Another thing to try is CCleaner - Download
click under Free, download from Piriform, be mindful of adding a tool bar. Use CCleaner's uninstall function.
