Hello there Neale,
Sorry to have to tell you this, but Take Two was a feature of Easy CD Creator 4 and 5. It was not in Easy CD & DVD Creator 6, and it is not in Roxio Easy CD and DVD Burning 2 [which you call ECDC2, and which is merely a cut-down version of Creator NXT 7]
There's no way you're going to get either version 4 or 5 running in Windows 10. I'm sorry, but if you ever use a specialized program like Take 2 or BackOnTrack to make a backup, you really need to store a bootable copy of the operating system with a running copy of the backup program installed in it. Otherwise, if you update or "upgrade" your operating system and the old programs stop working, you can lose access to your backups.
If you search on the Internet for .TK2 files you might be able to find and buy a commercial multi-file-reading program which will read your old backups, but is it worth the cost and effort?
