Reinstall Corel Draw x18

My Surface bit the dust.  I purchased a new Surface Pro 8 and ran into a wall when I needed to re-install Corel on it.  I had upgraded my Desktop to 2019 and want to run Corel 2018 on my Surface Pro 8.  But because I do not have an earlier version on the Pro - I can not install my upgrade version.  I am really stuck as to know what I can do.  My earlier versions on disks will not install at all in Windows 11.  Any ideas as to what I can try?
