Hello dear friends!

The system loves to cheer up the user with its unexpected error messages. Sometimes such a message resembles a blow to the head with a dusty bag: you sit to yourself, you don’t blow your mustache, when suddenly - crack! - "Here's to you, grandmother, and St. George's day!". And most importantly, damn it, how it’s all out of time! Common situation? This situation is especially familiar to gamers who, after installing the game, flap their eyelashes in surprise (clap and take off): what kind of "balalaika" is this?!
So, as you may have guessed from the title of the article (surprised by your insight), the topic is dedicated specifically to the players, or, as they call themselves, "gamers". Look!
You bought the object of your desire - a super game that was released a few days ago. Clear stump, you immediately gathered to "use" it. Installed? Cool! But when you start the game, you get this "game plot": "The application failed to start because d3dx9_25.dll was not found. Reinstalling the application may fix this problem".

What should you pay attention to? Look at the numbers that accompany the message: the numerical value of the file may differ slightly from what you see in the article. For example, the file might look like this: d3dx9_26.dll or d3dx9_27.dll. But this does not mean anything: the problem is still exactly the same as with the d3dx9_25.dll file. This I mean that the "teapot" - a gamer, looking at his numbers and the numbers in the article, will think that his problem is different from the one described. This is not true: the problem is the same, only the digital signature is different! Let's go further.

We turn to the essence of the question: why, in fact, did this message appear? And everything is very simple: you have an old version of DirectX - have you heard of this one? Enter the game disc and choose to install (update) the DirectX version. Where to look for it? So, like this: go to the folder where you have the game installed. For example: "Start" - "My Computer" - local drive "C" - Program Files - and then look for your installed game that does not want to start. Having found the folder with the game, open it (folder) and find the file you need - dxsetup.exe! It is called the same everywhere: dxsetup.exe - means installing DirectX. Open it and install the new DirectX. Now you understand how to resolve the message about the missing file d3dx9_25.dll.

In parting - a few words about what this very "DirectX" is. This is such a special set of virtual equipment that ensures the adequate operation of a multimedia device. And since devices are constantly being updated, the version of DirectX that is installed on your computer may not always work adequately with the new hardware that you have installed. Solution: install the appropriate new version of DirectX.

Well, if you are bored with these endless errors, then maybe you should turn your attention to the console? Yes, yes, I know that there is some enmity among the so-called "console players" and "bakers" ... But think for yourself, what is more important to you: games or fixing endless errors? That the Playstation 3, that the Xbox 360 can be flashed without any problems so that they allow you to run downloaded games: for Xbox "and I recommend this service: http://xboxflash.ru/proshivka-xbox-360 in Moscow, but anyone can flash a PS3 with minimal intelligence and the Internet: just type in Google "firmware ps3" and follow the first link.It's not difficult at all.

All the best to you and see you soon!
