If this registry key is removed or a particular value in it is altered, then the suite is immediately disabled. In the case of EMC 10.0, no applications will start when their icon is clicked and the suite becomes unresponsive. In the case of the 9.x software an error tells the user that "The trial version of this product has expired" and nothing else will open after that.
The reason this registry key is so fragile is that a placeholder called "TempVector" has been mistakenly left in the registry instead of being replaced by a file path. Any reasonably effective registry cleaner detects the error and removes the registry 'twig' with the placeholder. Unfortunately however that makes the 'branch' with the acivation data key invalid according to Registry rules, so next time the cleaner goes through the registry that crucial key gets removed and EMC is disabled.
The only way the software can be made functional again is to replace the key with its proper data value. This can be done by
(1) Reinstalling the software - the key is regenerated and its value calculated during install.
(2) Importing a copy of the key previously saved from that system - the key is unique to each system and a 'foreign' key won't work
(3) Running Roxio's "repairer" utility for that version of the software. - You give to the utility the CD-Key you used to install the software, and it will regenerate the data value for you. It will also correct the error so that you can use registry cleaners once more.
The repairer for EMC 9.x can be downloaded from HERE repairer9.zip 107.04KB 81 downloads. It has been written for and will work on version 9.x [including the Vista compatible RedBox Easy CD & DVD Burning version 9] only. It will not turn the trial version into a full version, or remove the time limit.
For those experienced at registry editing who would like to correct the registry error without waiting for the suite to be disabled, the value 'TempVector' in the key should be replaced by 'C:\Program Files\Common Files\Roxio Shared\DLLShared\rsl.dll'
In my 9.1.074 build 910B74I, R04 the key to fix is
For my 906B10N.R04 it was
In Easy CD & DVD Burning 9.0.554, build 905B54T,R01, the key is
Not all version 9 builds show this problem. If there are any affected builds I've missed, you need to make the same change to the corresponding key in your build.
