You must be on a very old W10 version or not even using Windows 10. All known methods to run old clients, one by one, were killed by cumulative Win10 updates. If you find another workaround and make it publically known, MS will definitely include a patch that negates it in one of their upcoming updates.


Not true, take for example L2oldskool C3 client, runs fine under latest Windows 10, and their launcher.bat was made long time before Windows 10 cumulative updates.
