Lol, no, I need 3 or 4 clients I can launch 2 and that's it. Can't third. I have great pc, but just can't launch the third one. It shows no error, just does not start. I just wanted to try the idea to install second copy of L2. But I can't. When I mount the ISO file it only allows me to Repair, Modify, Remove the existing copy. I does not have an option to install second copy

Still nothing. I can launch only 1 from each installation. :/ Looks like it's coded in my version of l2.

just copy whole your lineage catalog... and aplly new patch

we don't use any patches scions of destiny + some install from server. i did it as you wrote. copyed old folder, uninstall, install and from both tryed to launch 1 by 1. got to 2. that's it.

dunno...

I found out that we have limitations set on our server. So only 2 clients. Perhaps when we move to Interlude something will change. Will have to use my other PC's :/

Found a way. You can rename l2.exe to l2.exe.exe and it works fine. But I don't know if one can get banned by doing so. If there is a for GM to see that you're running clients from same PC. But I doubt that they can see your MAC address, 'coz IP addresses can be the same for more than 1 pc. Hopefuly I won't get banned.

on some servers its allowed
