I have installed RealPlayer many times from the bin file available from real.com. I think brjoon is doing something wrong.
First of all, you should download the bin file, not the RedHat package. As the bin file is downloading, click on Installation Instructions on the first Real.com page (it's right under the button for Free Download). If you have popups blocked, it might not appear. I'm not sure about that. But if you don't see the Installation Instructions window, unblock popups for that site.
Once Installation Instructions appear, just do what it says. You have to switch to the directory where RealPlayer10GOLD.bin was downloaded to. Open a terminal in that directory. Become root by doing su and giving your root password. Make sure you're still in the same directory by doing
at the command prompt. That will list your present working directory. Do a
command to make sure RealPlayer10GOLD.bin is there.
Then follow the directions in the Installation Instructions screen. As root, run
chmod a+x RealPlayer10GOLD.bin
at the command line in the terminal window. This makes RealPlayer10GOLD.bin an executable file. The rest of the instructions won't work if the file is not executable.
Next, still as root, type
at the terminal prompt. You MUST type ./ before the name of the file because Linux won't run a program that's in the same directory as you're working in unless you first type ./ . This is for security reasons.
Now the RealPlayer file will ask you where to install RealPlayer. You must have write permission in any directory where you want to install it. As root, you can put it anywhere you want. If you ran the same file as user, it would install in your home directory. If it doesn't give you a default, you could select /usr/local as the location. I'm sorry I don't remember what choices you get or I'd be more precise. I always type
as root when I've installed something, just in case new libraries need to become known to the system. It can't do any harm.
Once the installation is complete, type
at the terminal prompt so you become user again. Then type
to see if the setup for RealPlayer comes up. If it doesn't, switch to the directory where RealPlayer was installed and find the
file. At a terminal prompt in that directory, type
to start the setup. If you can't start RealPlayer except in the directory with realplay, you need to make a symlink from the realplay executable to a directory in your path, such as /usr/bin.
If I didn't forget something, these instructions should work. I've done them dozens of times, probably.
Let us know if anything is unclear.
