I really download the Scala installation files, in fact, is a compressed package, just need to extract the files can be!
You can also download the MSI suffix file on the website to install it.

The installation process is as follows:

The advantage of downloading the MSI version is that the environment variable is automatically configured, otherwise you need to manually set up two environment variables.
Scala_home environment variable, which points to the installation directory of Scala.
Path environment variable, to contain the value of%scala_home%\bin.

2. Install Scala 2.9.2
After the download is complete, execute the Scala-2.9.2.msi and follow the prompts to install it step-by-step. I installed it here in C:\scala.

4. Installing Scala in the Eclipse IDE
Scala officially offers three plugins that support the eclipse, NetBeans, and IntelliJ idea development environments, respectively. To install the Scala plugin under the Eclipse IDE:
Select the Eclipse menu item Help-->install New Software ..., click the "Add button" and fill in the following values in name and location, respectively:
Name:scalaide
Location:http://download.scala-ide.org/releases-29/stable/site
then step through the installation step by step until the installation is complete.
to restart Eclipse, you can see the new menu and windows-->preferences have Scala options.



5. Precautions
Note that, officially, the Scala IDE plugin currently only supports Eclipse 3.6 and 3.7 and does not support the latest Eclipse 4.2. After the author tests, it is true that the Scala IDE plugin cannot be installed in Eclipse 4.2.
In addition, Scala officially wants to adjust the heap memory of the eclipse runtime to more than 1024M. :
