How to update program

OK, when a new program version or update is avaiable, how to I install it?
If I uninstall WD and reinstall, I just get the same program, complete with registration code and problems, as I had before.

All you need to do after downloading the update, is close WD if it’s running and then open the file you just downloaded. The program files will install over the verion installed and you will retain all your settings and data.
