**TYPE defines the installation method
Setup indicates that the installation is entirely packaged into a Setup.exe file and downloaded to your computer before execution. This method is more time consuming the choosing a Execute version but it would be necessary if you wanted to download now but execute the installation later. It would also be necessary to use "Download" if you wanted to download to one computer but install on another..  NOTE: If you are asked whether to "Run/Open or Save" the file after it is selected, answer "Save".

PDF indicates this is a document in Adobe PDF format. You will need Adobe Acrobat Reader to view this file. It can be obtained by clicking on "PDF" from the row and following that link.

Execute indicates that the installation is executed immediately and directly FROM the web site and only those files found to be needed are downloaded. This is the recommended method if you want to install at the same time you are downloading.
NOTE: If you are asked whether to "Run/Open or Save" the file after it is selected, answer "Run".

Zip File indicates the package is a compressed file using the Zip compression protocol. The file is self extracting and no special software needs to be installed on your machine.

Standard indicates the package is a standard uncompressed file which can be copied to your hard disk directly with no installation step..
