I don't think you can "install" anything on a router. And as far as the CD's that must have came with it, they're unneeded, they essentially just install software to make dummies mess around with router's basic settings. Ironically, even though I call that software dummy-ware, I don't know how they often work having only spent minutes on some and preferring the router's page.
I can't offer you any solutions, but I can offer you some help or tips to figure out your router yourself.
This is assuming you don't know, but Google your router's model number. Don't bother including the maker/brand name unless you get multiple unrelated results. Most times a model number will be unique to a brand itself. It might also help to Google it with keywords like "Default, Login, Pass, Password, User, Gateway" You want to find out your router's default information so you can get into your router settings. If you used the dummy-ware off the CD, it may have gave you chance to change your password, in which case use that password of unplug/reset your router to make it go back to default.
Same with finding your default passwords on Google, you want to find your default gateway, in which case google your Model number and "gateway" together. But most often times, I find that 192.168.1.1 is the default gateway on most routers. In anywise, you might not need to Google it but view the Properties/details of your network adapter:
How you get to that depends on OS but its commonly found in Control Panel and Network Connections even though there are easier shortcuts and ways to get to it. Anyways take your Gateway, punch it in your URL bar/Browser like you're going to a site like Yahoo or something, and enter your login info if prompted. From there you might be able to learn about your router and maybe setup your WEP system. Otherwise wait on someone to post something that would be more useful to you or ask more questions. The more questions/information you post, the greater the chance at getting help. Personally I have no idea what Network Magic Pro is, what it does, or what make is it even for. Just sounds like a dummy-ware wizard to me or one of those one button touch auto-setup systems.
