Hi,

It seems as though both file contain the same license package, and as one is already installed, the installation of the second fails.

If you run the command show license usage it will tell you any licenses that are already installed and in use. For example:

c9372-1# sh license usage
Feature                      Ins  Lic   Status Expiry Date Comments
                                 Count
--------------------------------------------------------------------------------
NETWORK_SERVICE_PKG           No    -   Unused             -
LAN_ENTERPRISE_SERVICES_PKG  Yes    -   In use Never       -
--------------------------------------------------------------------------------

If you then run the command show license the first line of the output will indicate the file that was used to install the license. This will most likely be the License_SAL1920F30D_27.Lic file you show. If you then run the command show license MDS201507172040360360.Lic, you can see the license that file contains.

If they are the same e.g., both LAN_ENTERPRISE_SERVICES_PKG, this would explain why the second gives an error when trying to install.
