I have installed my software on D: drive(non-system drive). Due to some reason have to reinstall windows so C: drive is formatted. Now I want my previously installed s/w on D: drive to work. How can I achieve this?

Reinstall your software.
Unfortunately, there's no working way to get your new Windows installation to recognize the old software installations. Your data and everything you might want is still there, but Windows applications often install DLLs and other dependencies into the system folders and add information to your Registry. The only way to get that back exactly as the application would expect is by reinstalling it.
There's no benefit to installing application software on a separate drive/partition. There is every benefit to isolating your documents and other user data on a separate drive/partition.
