Hey, I thought I could share my experience with downloading and running a Voice Changer program I saw on GitHub as well as the issues I experienced running it on my machine.
It's worth noting, my PC specs are kind of basic (intel-core i3, integrated graphics). The program itself runs some commands by using the command prompt (CMD). When I got to the step in the instructions that required typing start_http, it was intended to open a CMD window and start the service. Instead, the CMD window opened quickly then disappeared without any information useful to me.
I went through a series of fixes (updated drivers, installed dependencies and other such things), but there seemed to be a problem. The issue may be technical requirements that the program needed that my hardware or OS doesn't support fully.
In addition some programs require administrator privileges to run commands through CMD and create the service. I attempted to run CMD as admin while running the command again and it still closed instantly.
