Summary:
We have updated to the latest Rainbow driver, running CiUsafe successfully. Updated IE and Windows to the latest version. Running the application on another computer successfully. But when we startup on this computer we get software protection failure immediately on startup. But we found that of some reason that the cryptography key recently has been changed, as mentioned in KB 3052 section nr 1.  

Solution:
Delete the cryptography key under :

\Documents and Settings\All Users\Application\Data\Microsoft\Crypto\RSA\MachineKeys

Start IE and a new key will be created, in consequence of this the key will be found.
