What are the analogs of sandboxie for running multiple applications on 1 machine?

Question

Virtualization

Actually there is a program that does not allow you to run more than 1 copy at the same time. Now I use sendboxie, but it is not very convenient, because I don't need virtualization, I just need a way to run one application n number of times within the same operating system. The name of the process and the program itself cannot be changed, because of this it will not start.
What methods / programs are there that can run such applications n number of times, preferably for this purpose, and not analogues of sendboxie

Answer 1

Make a portable version - each version runs in a container (run from different directories), they may not see each other.

Answer 2

1. use simlink, hardlink, junction
2. make several copies of the folder with the program
3. point 2, but with "linking" the necessary files (if there is a database or something like that)
4. try to find the launch keys or just try to run with any keys

Answer 3

Depends on how the program determines the presence of other copies.
