Recently, the mainstream method to insert pseudo code in the paper is Aurora, but I encountered various problems when installing it myself... This old plug-in is too troublesome.
Normal installation should only support 32-bit Office (who still uses 32-bit these days).

Operating system: Win10
Office version: 2019, 64 bit

Aurora + miktex2 needs to be installed 9， Download address

1 installation

1. Install MiKTeX 2.9 first
2. Then install Aurora without miktex
3. Then run keygen to crack

(many online tutorials say that the time is changed to 2009 or 2005, but there will be problems after the time is changed, so I didn't set it like this.)
They are not installed in the default path, but installed on disk D. facts have proved that it does not affect the use.

2 setting

Set paths, find the corresponding file in your installation path and fill it in.

Then you can write some simple code. such as

3 pseudo code configuration

The pseudo code needs to install additional Packages. The common saying on the Internet is to enter in Packages, but I always report an error

3.1 setting the Rendering method

3.2 [important] installation package!!!
This is the reason why I failed to install the online tutorial at the beginning.
Run miktex console as an administrator Exe, where is your location

D:\Software\MiKTeX_Aurora\MiKTeX\miktex\bin\x64

3.3 add package
There are many examples on the Internet, but there is little difference. Here are some excerpts for standby.
I used the second one. The first package looks more, but the second is enough for common code.
If you use the first one, you will still report problems running latex. It should be that you need to download other libraries. Don't bother yourself first.
