CS5 |purchased as CD bundle in 2010| - how to download on new PC without CD-rom

Dear IT experts!

I have have purchased in 2010 CS5 Master Collection, which I installed on my laptop at that time. Now I got a new PC without CD-rom and I need to install there all software that I bought in CS5 bundle seven years ago.

I do not have any external CD-rom and reluctant to buy it as I will not need it later, since everything now is distributed on USB or via download links.

How should I get this product once technology changed? Is there a link to download CS5 Master Collection?

Thanks in Advance!
