Endnote 3 (with update) can't install

I have used my old Endnote 3 (and later Endnote 10 update) for years. But I purchased a new computer recently and it won’t let me install Endnote 3 because it’s incompatible with my Windows 10. I have an updated CD (which I’m assuming is compatible) but it won’t let me install the original program, which is required.

Any ideas?

Please help.
