This error is caused because CardExchange® has been installed under the administrator account and the default location of the Database folder has not been changed to a location where all CardExchange® users have full read/write access. Now another user tries to activate the license but the system tries to install the license into the License folder where the user has no access or sufficient rights for.

When this error appears, the actual activation has succeeded but the result cannot be stored. The solution for this is described in the Online Installation Guide at section "Activation errors".
