Wait, I should check if Parashara Light 70 is a real product. A quick search in my knowledge base: Parashara Software is a well-known company in India that provides Vedic astrology software. They have various versions, including different editions with varying features. "Light 70" might be a specific version they offer, perhaps for a limited period (70 days?) or a trial. The 70 could refer to a trial period, but I'm not sure. The user is asking for installation on Windows 7 64-bit, so I should focus on that.
