After installing the latest free update for Dell users for the Cyberlink Media Suite Power DVD from version 12.0.3324.55 to 12.04303.55  getting error message "The integrity of Cyberlink PowerDVD is at risk.  Check anti-virus software for malicious activities or try reinstalling Cyberlink Power DVD.  I could not play any dvd with Power DVD.  I restored the system to an earlier restore point but Power DVD still did not work so I had to download the CyberLink Media Suite version 10.0.1 from the My Dell Download site.
Power DVD is now working but with the original version 10.0.4825.52.  Now when I tried to install the
 latest update again, I get a message that this update is not valid for this version of Cyberlink software and the installation aborts.  Is there anyway to go back to version 12.0.3324.55 version before the
update attempt?
