Install IPFS 0.4.18

Dear all,
I’m new here.
I have installed IPFS 0.4.17 and I would install IPFS 0.4.18.
I’ve downloaded the go-ipfs new version but I can’t install it because I have the previous version installed. I get an error when i lance ./ of the new version.

What can I do?

Thanks and best regards.

What’s the error you get?
