I have a similar problem: I can't install my Adobe Photoshop Elements 6 software from my CD Rom because it seems the hole on the CD Rom is smaller than the space provided for using CD Roms in my new computer. I also checked if it would be possible to install it using an external DVD Rom device but it is the same issue, the CD Rom doesn't fit. So, can someone tell me please if there is an available download of the same software (version 6) for Windows 10 (I could use my version 6 perfectly with Windows 10 in my old computer) that I may be able to install in my new computer. I don't have my old computer now so it's impossible to transfer anything to my new one.

If you look at the response made in the thread that gener7 posted above, you will see that, Elements 6 is not available for download. The earliest available is 7. I recommend upgrading
