Libtheora.dll error

[doomdoom]

Hello, I have followed the tutorials steps for beginners, but when I try to see a model using HPL Helper, I get an error with a Libtheora.dll. I would like to know what it is, and how I can fix it.

Thanks,
Greetings!

What is the error?

[doomdoom]

"Error to initiliaze the application because libtheora.dll was not found. The reinstallation of the application can solve the problem". But I have reinstalled them and yet the error is there.

Using a search engine, I found hits for patching the game. Have you downloaded and installed the latest patch?

If the latest patch is version 1.1, yes, I have installed it. The game runs perfectly, but are the Viewers of the HPL Engine that fails to load/open/start. May be this Libtheora.dll is related to video codecs?
