SIMCity 4 Deluxe Install problem

I am trying to install and have mounted files a and b but when I'm installing it gets to 48% and says it cannot read or find Graphics Read.sgr and it makes me quit the install. How do I fix this? I assume if I ever get to the Video Cards.sgr it will have the same problem because there is also no emblem coming up for that. please help me out, thanks.

Hello,

Please open the .rar file you downloaded using only WinRar, which can be downloaded from www.games4theworld.org . (If you use any other software than WinRar, like WinZip or 7-zip, the files will get messed up!)
When you've opened the file using WinRar, select áll the files in it and drag & drop them to a folder on your Desktop. When the extraction is done, close the .rar file and open the folder on your Desktop.
Now, start by reading the included "# Installation Guide.txt" and you should be able to get the game to work yourself. Good luck!
