Question : Using install script to get directory path of the installation

I need install script to get the  directory path of the installation and write it to a key. I know how to write to the key, I just need the name of the function that returns this and it's return value so that I can put it into a variable to be used by RegDBSetKeyValueEx. Hopefully an easy 500. Thanks.
