How to open two world editors at once?

[Super Mage]

The reason why I want to do this is because I want to compare the units' stats from Reign of Chaos and Frozen Throne.

Surely that would be something you can look up online, right? At least I bet it's faster than figuring out how to have two instances of the editor

Opening 2 World Editors in one instance is literally impossible. However, you can still open 2 maps in only one World Editor and switching between those using the "Window" menu.
As Dr Super Good said in this old thread 9 years ago, there are only 2 possible ways if you still want to open 2 WEs in one instance:
-Modifying an executable file regarding the process declaration so that a new instance of WE doesn't interfere with the existing ones. The only possible thing you can do this is Sandboxie.
-Use VMs (if available) with the WE process in them. This is not recommended because of VM graphics instability and might led to unwanted issues.

2 world editor -> get another version of warcraft 3. You can run world editor from V1.29.2 and V1.30 at the same time.
