Hi Menace nz
if the single file is ivpbot.dll
You need to read more on the forum and visit
http://ivpbot.bots-united.com/
The key thing in all this is that ivPBot is a metamod plug in. This means you must have metamod working.
At server console type meta list
metamod stuff is not loaded do a google search on metamod and study that and get it working.
Then start on ivPbot. At each stage check that metamod still works if not back track.
This was my working command line for HLDS E:\Games\SteamServer_v1120\hlds.exe -dll addons\metamod\dlls\metamod.dll
create metamod\config.ini
add this line(must be metamod117):
gamedll ivpbot/ivpbot.dll
All the above is if you must try ivpBot.
As Pierre says if you realy want to get into bots get 'sPlOrYgOn's POD-Bot 2.6mm ' as they are supported and under continuing development. I can recomend POD-Bot 2.6mm.
Hunt.
