Hver socketadresse (protokol/netværksadresse/port) kan kun bruges til én ting ad gangen. Kontroller, at der ikke er andre tjenester, f.eks. IIS, eller programmer, som forsøger at bruge samme port, og prøv derefter at aktivere plug-in'en igen.

One usage of each socket address (protocol/network address/port) is permitted. Verify that other services (such as IIS) or applications are not attempting to use the same port and then try to enable the plug-in again.
