You're probably wondering why I am telling you how to install such a basic program. If you're asking this, I would assume you know how to, but to some people, installing things is a major event that is scrutinized very carefully. Even more concern occurs when Coolbits asks if you want to make a new entry into the registry. To many people, Registry = No-Go.
NVmax first - Unzip the file if it came zipped and then run the file called NVmax.exe - how nice of them to name it that. When you have executed the file, it will act like a normal installation and then open the program once you're in there. Very easy.
Coolbits is just as easy, but the area you tweak from is a maze to get to. After you have downloaded it, run the file and say "yes" to the question about adding the information from the Coolbits file to the registry. This will not, OK, shouldn't, do anything bad to your system. The notion that fiddling with the registry is a no-no, is completely and utterly wrong if you do things the right way, following the instructions.
