In the past months I've been bombed by countless e-mails and private messages in various sites about the DLL API version Doom 3 error.
It seems a lot of people have difficulty to check their Doom 3 version, confusing the patch 1.3 with the 1.3.1.
Is just a little number, but it changes a lot, because mods with custom dlls, need a specific version of the game.
So you have that API DLL error and think to have the right version of the game? Well you haven't, so read below.
Readme text files, those damn text files. Most of the people just don't read them for unknown reasons, but before starting mailing about some problems, this is the first thing to check.
Usually this text file contains all the information about the mod, including installation instructions and the version of the main game required to run the mod. So in the case of Doom 3 if you read 1.3.1. required,
thats the one update you need.
2- HOW TO CHECK YOUR DOOM 3 VERSION
There is a simple way to see what version you are running the game. So, run Doom 3, open up the console, to do so press CTRL+ALT+TILDE, for some european keyboards the TILDE is the slash down the ESC button.
Now you have your console open, you will see some random lines you won't need to know what they are about. You have to look at the bottom right of the console.
There is the version number, so here the differences about patch 1.3 and patch 1.3.1:
1.3 = DOOM 18.104.22.1682
1.3.1 = DOOM 22.214.171.1244
You see the last number is different.
3- UPDATE BUTTON
The last way to check if the game is updated to the latest patch, is to press that button on the mainmenu with written on it UPDATE. This button will check automatically the latest version, and it will ask you to download the patch if needed. So give it a try.
I know not everyone is into that tech stuff about patches and version numbers and I blame Id Software for not just calling the latest patch 1.4. But well, with this article I hope to solve the problems of who didn't figured out the differences about patches, and the DLL error.
