Error initializing RainCAD registration. Requested registry access is not allowed.

We are getting an error after running the application for standard user. If we run the application from Administrator account, it works fine. But for standard user, we get error :Error initializing RainCAD registration. Requested registry access is not allowed.

For security reasons we do not want to provide administrator privileges to users. All user accounts are standard accounts on windows 7 64 bit computer.

Request you to please help us with this error.
