You need to pull the full error message from the 'EPO4xx-Install-MSI.log' created as this is not enough information to assist you i'm afraid.
You can then use the McAfee knowledge base to search for possible solutions.
Follow the 'search the knowledge base' link.
If there are still problems i'd suggest opening a support call.
The installer is complex and may require some detailed analysis to identify root cause.
you can find EPO4xx-Install-MSI.log as start>run and type %temp%
