We cannot provide or allow links to any software that is considered a "multiclient hack", just as a precursor. Users typically use VMs or sandbox software such as Sandboxie to run multiple clients. However, you should be aware that if you run multiple clients from the same IP, on the same PC (not using a VM), GGG will know at login due to mac address hashes being the same. Since they have a strict policy on this, you'd most likely get caught sooner, rather than later if you do this.
