Error: "CRC error: The file C:Program FileCyberLinkPowerProducer

Q:  I was in the process of installing the Power Producer Express software
    when I received a CRC error.  The following message popped up:
 
        CRC error: The file C:Program FileCyberLinkPowerProducerExpress
        ltfil1ON.DLL doesn't match the file in the setup's .cab file. The 
        medium from which you are running the setup may be corrupted; contact
        your software vendor.
 
    There were 3 boxes below this message;  Abort, Retry, and Ignore.  
    I repeatedly selected Retry but the installation would not continue.
    The installation stopped at 36%.

 
A:  The file, ltfil1ON.dll is not one of our files or required for the
    install. This may be part of a virus or spyware that is or was on your 
    computer.  Please make sure that you are using a good anti-virus program
    with the latest Virus Definitions installed. You may want to do a little
    research on this and find a way to remove the reference of this file from
    your computer. Unfortunately, we are unable to solve this problem for you 
    as it is user specific and is not related to our software or install.
 
    You can try completely uninstalling the software and hardware, turning off
    all applications running in the background and then re-installing the 
    software. After you have re-installed the software, power down your
    computer and re-install the hardware. Power up your computer and see if
    you receive the same error.

    If the problem persists, you might wish to try copying the contents of 
    the installation CD onto your hard drive and run the Installation from
    there.
