You are welcome and don't worry about the English, it is good..
If you had 8.17 already and it was working with PP2000, then what you needed is the APP v8.35 folder, this is for people who want to leave their DiagBox 7.82/3 and update PP2000 and Lexia.. You need this:

But you can also try renaming your APP folder to APP8 and copying the APP 35 again as per the procedure in the first post. Just make sure that you run the "Kill_DiagBox_Tasks.bat" as Administrator twice to ensure all processes are stopped.
Lexia and PP2000 will only run on 32 bit based systems, they rely on DiagBox but they need the version to be 7.
I am not sure if you need to reinstall, but I hope you don't.
