How do I uninstall Admin Mod ?
You don't. :D
Just kidding...
If you are trying to uninstall version 2.50.50 or later it's pretty simple. In the addons/adminmod/tools directory there should be visual basic script (.VBS file) with will uninstall Admin Mod for you. The only thing it does not do is remove the lines that try to execute the adminmod.cfg file from you listenserver.cfg and your server.cfg file but this is easily done by hand. For mor einformation about the uninstaller script see the Running the Uninstallation Script page of this manual.
It is important to note that if you use this uninstaller to remove previous versions of Admin Mod, the Admin Mod CVARs located in your (listen)server.cfg will not be removed either. You should remove these by hand after uninstalling Admin Mod.
If for some reason you can't use the uninstaller you will have to uninstall manually. Hopefully you were a good scout and made a backup of your original files just in case. If so, just restore your old liblist.gam file and all is done.
But if you didn't (shame on you), it's really quite simple. If you are
uninstalling a 2.50 version to keep things clean and tidy, you should
remove the Admin Mod specific CVARs from your server.cfg or listenserver.cfg
(whichever one applies to your situation). then remove all your Admin mod specific config files (users.ini, wordlist.txt, etc..) from the <mod> directory.
If you are uninstalling a 2.50.50 or greater version you should remove the line "exec addons/adminmod/adminmod.cfg" from both
listenserver and server.cfg (as before depending on which one you use.). The delete the <mod>\addons\adminmod directory
Then edit your liblist.gam file in your server's mod directory to return the gamedll file setting back to "dlls\mp.dll" (if you're using counter-strike for Windows) or "dlls/cs_i386.dll" (in the case of counter-strike running under Linux) The gamedll name depends on the mod you are using.
That's it.
Unless of course you want to use the windows uninstallation script, in which case you should read the Running the Uninstallation Script page.
