Make sure you download the correct version update type for your
system. Remember the 32 bit version will not update a 64 bit system and

button followed by Control Panel. In Control Panel, Click the System Icon.

the 'system' section. Under 'system type' you will see either 32 bit
operating system or 64 bit operating system. Whatever operating system type
is displayed here is the 'type' you will need to download.
