change the location for Putty within RDM

Hi
How do I change the location for Putty within RDM? I had to delete Putty and reinstall Putty to a different location. Now when I double click on a host, I get the error:
"Unable to find the Putty application. Make sure its installed and check the configured path in the application process."

How do I point Putty location to the new location?
Thanks.
