--------------------------------------------------------------------------------
Check complete. The overall result of this check is: Failed <
Problem: the installation detects that the system's primary IP address is the IP address allocated by DHCP.
Proposal: Oracle supports installation on a system with IP addresses allocated by DHCP. Before installation, you must configure the Microsoft loopback adapter as the primary network adapter of the system. For more information about installing software on a system with DHCP configured for S, see the installation guide.

--------------------------------------------------------------------------------
The solution is as follows:
1. Enter ipconfig/all in the command line to check whether there is a Microsoft loopback Adapter. If there is a Microsoft loopback adapter, assign it an IP address directly. If no lookback device is installed, transfer it to 2;
2. If no lookback adapter exists, open the control panel and select Add hardware;
3. if you select next, the message "Whether the hardware is connected" appears. Select Yes and click Next;
4. The list of installed hardware appears. Pull the slider to the bottom and select "Add new hardware device ";
5. When you select next, the system prompts "what do you expect the Wizard to do ?", Select "Search and automatically install hardware ";
6. Next, wait. Next, a list of common hardware types is displayed. Select "network adapter ";
7. Click Next and select the vendor and network adapter: Microsoft -- Microsoft lookback adapter;
8. Start installation.
9. After the installation is complete, the second local connection will appear. In this case, you can assign a fixed IP address to the Microsoft lookback adapter, for example: IP Address: 192.168.1.159; subnet mask: 255.255.255.0; Default Gateway: 192.168.1.1

In this way, the above Installation Warning problem is solved.
