Important Note

The installation package is compressed using WinZip 17. Other applications might not be able to decompress the package as different applications implement the ZIP format differently. A free alternative that was tested with the installer package is the 7-Zip application. 7-Zip can be downloaded from http://www.7-zip.org/.

After downloading the zip package, please first decompress it and then start the installation from the resulting folder.
Do not run the installation directly from within the compressed file.
