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.

well...thank you ,sepultribe

last night i tried to setup a prelude server,but failed.....

 

dont know why l2authd show these errors,i used prelude DBscripts.any1 knows?

 

OS:win server 2003 enterprise x64

Expand  

 

something in the DB connection config or wrong table names, there were 2 different prelude packs circulating back in 2004 afaik, they had some small differences in the db scripts.

 

can you plz reupload the pack the OP posted in this topic? or anyone else that has it?

 

ps: Error 42S02 indicates that object was not found in the db, in your case, tables server and worldstatus could not be located
