TextAssist 4.0 is a paid text-to-speech program originally created in the days of Win98.
It also worked pretty good when I switched to WinXP.
I'm posting this to let people know I got it to also work with Win7 Pro 32bit.
With Win7, after booting to Desktop, if you just click on the TA40 shortcut icon, it'll freeze (at least, for me it does).
All you have to do is start and play any .flv program for a few seconds first. I use FLVPlayer4free v.22.214.171.124. Then shut that down.
Then you start TA40, and it will pop up a window every time, asking you if you want to register it even if you've already registered it.
Actually, if you try to reregister your registered copy, that won't succeed.
So anyways, just click on 'No' you don't wish to register TA40.
Then it'll load and a movable mini-window will appear at the top of your Desktop screen to show it's ready to go, and it'll work as good as ever.
It's really a very good quality speech program, even though it appears to no longer be actively supported, and has saved me much money by not having to buy a newer program instead.
One other detail; if you click on 'show Desktop' (i.e. 'minimize all windows') with TA40 opened and either running a playback or ready to do one, it will lock up TA40 and you'll have to reboot to free it up.
