Product downloads

All product downloads are provided as regular ZIP or self-extracting EXE files.

Some older versions of Internet Explorer may corrupt the download of self-extracting EXE files and certain anti-virus products will block the download of regular zip files. If you experience a corrupted download, please try downloading via the alternative link which gives you the download as a password-protected zip file. This should ensure that you get a valid download.

To unlock a password-protected zip file use the password "bcf" when prompted - three lowercase letters without the quotes.

Linux users can unpack the zip files with 'unzip' version 6.00 or later. Older versions of 'unzip' may not support password-protected archives.
