Trying to apply/authorize a product license returns status 7315 "Product key is already activated on this machine. " Trying to delete/deauthorize a license returns Error 7334 "Unexpected authorization error. Please contact Support."
To get around the Status 7315 or 7334 issue the clear command from the command line License Administrator:
clilcadm -c <licensestring>
w64clilcadm -c <licensestring>
Users sometimes confuse the clear command -c for the deauthorize (delete) command -d. The -c and -d commands are not the same. As mentioned previously, the clear command should only be used to resolve status 7315 and status 7334 situations.
