Another alternative is, if the product you are detecting is an MSI, you can use Upgrade & UpgradeVersion elements and the OnlyDetect attribute to set a property if any of those MSIs are installed. The upgrade table can detect products other than the one being installed.

There can be multiple versions of the product installed on a system. There are multiple paths involved in detecting the product. How would people handle this for best practices given the following: The registry contains the path to the main executable and all other required paths for each version. Would people have version specific properties pointing to the individual paths, or is it better to write a table and have one property to tell me whether the version of the product is installed. Any help appreciated.
