Question

System administration

Good afternoon, I installed 3proxy on my home PC, it worked and decided to install it on my working PC, Windows 10 ltsc, I installed the same Windows clean, installed it - an error: Failed to open Service Manager: No error, re-read everything, tried three Windows, the effect is the same, 3proxy files are the same as on my PC. What could be the problem ?

Answer 1

Most likely the reason is blocking the opening of ports in windows.

Answer 2

To install as a service, you need administrator rights, run cmd.exe with administrator rights and do install from it.
