OK, 2.2.1 for ANYTHING above Windows XP and 2.1.3 is the last of that breed. I use XP sp3 for things other than the internet, so it doesn’t get connected to the outside world. I don’t know what you mean by “finalize”, but probably better to ask that in a separate post if you experience the problem in Audacity 2.2.1. It is very much recommended that you don’t connect an XP machine to the Internet as XP is dangerously insecure. XP is no longer supported by Microsoft, and we are not able to offer support for XP, though there is some information on this page: Audacity 2.1.3 is the final version to officially support Windows XP. The current version of Audacity will not work on Windows XP. The current version of Audacity is 2.2.1, and it is available (free) via the Audacity website:

There would certainly have been some bugs (as there are in all but very simple programs, but it’s so long since I’ve used 1.2.6 (many years) that I don’t recall what issues there were.

There’s nothing to stop you using Audacity 1.2.6, but if you have problems then you’re on your own.
