No, you can use the same CD and install it on other machines BUT you can only play one machine at a time. Since it registered to your account.
You can install World of Warcraft on as many computer as you want since there is no code required to install the game itself. However, you can only log on to an account from one computer at a time. If you want to run multiple computers at the same time, you will have to pay for another account.
It depends on what it is. If the files from the program are still on your computer, you can go to Windows Explorer and look for the "setup" of the program.
If you uninstalled a program accidentally and it altered your screen resolution, you may have uninstalled a crucial piece of software. You can choose to reboot your computer from a previous date. If you have a backup created of your system, you should install that, as that may reinstall that program. It may have been a graphic driver that was uninstalled. You can also take the computer to a computer repair shop, they can tell you what specifically and other ways you can get that back.
...thats more of a computer question
If you have your own computer with you, World of Warcraft installed on it and access to a stable internet connection, there shouldn't be a problem. If you're using one of the school's computers you can install the game on a portable harddisk and play it from there.
just put in the CD and install.
If world of warcraft is no installed on your computer you need to install it again. Your account is just there so you can get on the game after it's on your computer.
No
If you can not use CD's in your computer, then you can download the game from the official website and install it that way.
When World of Warcraft is installed, it asks you if you want to install Direct X.(only if you currently have a previous version)
You probably need to re-boot the computer. Most install/uninstall operations require Windows to be re-started to complete the process.
