Pretty sure this is the company I learned with: https://www.amazon.com/Individual-Software-Typing-Instructor-Deluxe/dp/B000F3BY84/ref=sr_1_12?ie=UTF8&qid=1463671216&sr=8-12&keywords=typing+tutor Mine wasn't 16th edition. 😉 But same company – logo looks familiar at least. It's targeted more towards kids, but same methods apply for anyone, and it's not overly kidsy. For example, you can play games for practice, or you can type articles.
IMHO, the key to learning to type is that, especially when using one of these programs but even when doing other typing, you have to refuse to allow yourself to look at the keys, at all. As long as you allow yourself to look, you won't improve. My parents used to make us lay a paper over our hands so we couldn't see the letters while we were typing, and/or put stickers over the letters so that we couldn't see the letters anyway. If you have an old keyboard laying around, you could always take off the keys and rearrange them so that looking at the keys messes you up instead of helping (just leave F and J where they belong so that they've got the little bump in the right place).
Also, my parents required we get over 95% accuracy and 20 WPM on a lesson before we were allowed to proceed to the next one, and no backspace allowed (otherwise we could “fudge” the accuracy). I don't know if this was an arbitrary figure they picked or if they had done research in picking it, but it worked well for me at least, so you might consider adopting this or a similar rule for yourself. Now I type about 90WPM on a good day, 80-85 on a bad day, but the basis from when I was young got me to where I am now (not that I'm old lol – just 25 😛 ).
P. S. Also, from related, Mavis Beacon is still available: https://www.amazon.com/Mavis-Beacon-Teaches-Typing-18/dp/B0014ZQMXO/ref=pd_sim_sbs_65_4?ie=UTF8&dpID=51BUtcXTKLL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0WCS8842EQNDR5KEDH8P
