Reinstalling DPM After Evaluation or Technical Preview


One of the common questions that I’m told is when you installed the System Center Data Protection Manager, is an evaluation version or a Technical Preview, when you try to uninstall to upgrade DPM error occurs that DPM is already present or that he is installed as evaluation.

This error happens in many cases, but the commonplace is when using a Technical Preview and uninstalling maintains the license key.

To solve the problem, just delete the license key that "left":

  1. Open the Registry Editor (RegEdit.exe)
  2. Navigate to the key HKEY_CLASSES_ROOT\Licenses
  3. Delete the key 830D982D-9ADC-4479-85CE-6474F7D00BB1

After removing the DPM license, installation occurs successfully.
