If the internet connection has been terminated before the end of the download (size does not match) or if the download procedure returned damaged data (it may happen during a connection) then the install procedure will fail returning an error message.

• Delete the downloaded file from your hard drive. Then try to download the file from the same source.
• If it fails again, try another source.
• If you still have problems, try to download the ZIP version. If you can unpack the ZIP file without problem, it means that the install file is correct.
