On this page you can download the utiltities which are needed to install drivers which complain about not being "intended for use with your computer model".

The utility is, like all other driver packs, made by Sull86 of micropctalk.com.

Model.txt Trick [Updated: 23/6/24]

What is all this talk about the model.txt file ?

Sony packs all the drivers and applications with a model check, very simple it just looks if the executable matches up to your model UX, this can be a pain in the but, specially for folks with Vista who want to downgrade to XP or myself (Sull86) who has a Japanese model UX.

How do you trick Sony's executables ?

We will go over how to do the trick in Windows Vista and Windows XP.

Windows Vista

• Locating the model.txt, you should find the file in C:Windows. If you do not see the file, you will need to grab the first Sony driver (labeled with #1) and run it. If it fails with a message that it is not designed for your computer model, the model.txt file will be created, and you will have to follow the steps below. If it does not fail, congratulations, you can install all drivers straight away and turn back on UAC afterwards!
• Once you've found the model.txt file, open it (in Notepad) and change it, so it contains the following information:
  Model = “VGN-UX (enter the model for which you are downloading the drivers)” Example: Model = “VGN-UX380N”. Save this as model.txt in C:Windows. (If you get an error that you don't have permission to save here, first save it to the desktop or 'My Documents', then move the edited file to C:Windows using the file explorer)
• Right click on the edited model.txt file, scroll down and click on Properties, at the top of the window click on the Security tab. Let's make sure we have full permission to do what we need;
• You should see an Advanced button at the bottom right corner of the window. When you press the "advanced" button, a new window should appear, at the top of this window select the Owner tab, at the bottom left corner of the screen press Edit, now click on your username and press OK. You will probably get a security window that says “If you have just taken ownership of this object, you will need to close and reopen this object's properties before you can view or change permissions” that is exactly what we are going to do, press OK and keep pressing OK until all the property windows are closed;
• Now let's go back to the model.txt properties to change the permissions so that the file cannot be written to. Right click on the model.txt file and click on Properties. At the top of the window, select the "Security" tab. Near the top of the window, you should see “Group or user names:”. For the first user name listed, click on it and then click on the Edit button. A new window should appear and now you should put a check mark in the box to deny Write permissions. Do this for every user listed in the top section labelled "Group or user names:" (you can click on the user name to change permissions). Press OK to confirm and close all other properties windows by clicking OK;
• Once finished, restart the computer;
• If you have followed the instructions correctly, when running any executable packed by Sony you should get an error, but let it continue on and it should finish without any problems

Windows X

Alternate method for Windows XP or Vista

Another way to get rid of the model.txt completely, unpack any application/driver with a program called WUN or Universal Extractor 1.6.1  (note by Arjan: This is the download shown to the left on this page and it will redirect to the original application's download page, which is still online). all this does is removes Sony's executable with the check
