• The installation process is very simple, that is, after clicking the installation package, go all the way down to "Next" (the default installation is on the C drive, if you want to install it in another location, remember to modify it).
• The process is relatively simple and will not be repeated here.

3. Install the root certificate (computer)

• After starting the application, it will prompt that it is currently a 30-day trial version. The solution can also be obtained from the official account, so I won’t go into details here.
