That makes no sense as the system should have a 500GB drive. Can you post a screenshot of the properties of the drive? My Windows 10 and programs install only takes ~52GB. Also can you post a screenshot of the Drive Management screen? (Let us know if you need help getting to the screen.) It is possible that the drive is partitioned with a really small system partition and a much larger second partition.
In direct answer to your question... yes and no.
If the software allows you to choose an install directory the answer is usually yes. If the choice is not offered the answer is no.
