My family frequents the library and I occasionally take out old CD-Rom games for the computer. We have found a wonderful (and kosher) children’s game that asked us to download it to our computer so we can run it for playing. It is now installed on my computer. I was going to delete it and take it out again another time since we only borrowed it from the library. However, the company that manufactured it no longer makes it (I called)… therefore, do I need to delete it from the computer and re borrow it again from the library or am I allowed to keep it on, and use it as desired since I cannot buy it anyway.
You can keep it there. This is because downloading for private use is a controversial matter, plus in your case the company doesn’t even sell it anymore.
