How can I install the game without a CD drive?

I bought a PC game again after a long time. Unfortunately I only saw at home that there's a CD. I thought it would work without a CD and only with a download and code.

My new laptop no longer has a drive. Is there a way to install the game without a drive and to play later?

On igg games. Net there are all games:-)

If it is on steam etc. Just enter the code and download it or use an external cd drive

Unfortunately you forgot to tell us which game it is.

If it has to be registered via an online platform such as Steam, you don't need the CD / DVD anyway.

I have to download Steam, right? I'm technically pretty bad.

Yes

But is the game on steam at all?

Yes, it is. Support wrote me.
