Hi, @shadowfruit8
Use my host file.
I have not written anything. It is the default.
Please download the attached file to " C:\Windows\system32\drivers\etc ".
After that, as shown in the screenshot,
Refer to the area circled in red and check the box.

Screenshots are in Japanese.
You can proceed by looking at the icons.
After setting up the screenshot,
hosts - edit the name of copy.txt to hosts.
When you are done, make sure Horizon Client can be installed.
