To solve the demo license issue:
Go to the search tab and type ‘command’ and click it.
Type “ipconfig” then space and click “enter”.
At the bottom side, under the wireless LAN adapter, Wi-Fi - IPv4 Address. Check whether the main PC IPv4 address is the same as the client IPv4 address or not. If not, change it.
If the IPv4 addresses are the same, then go to activate the license.
