HP Deskjet 5740 and the notorious hpf4ec10.dat

September 7,2015: This article is pretty much obsolete. To my surprise , though, HP’s drivers have been updated, so there should not be any problems.

This is gonna be a short one. It is about a problem that came up when i tried to install the HP drivers of my “ancient”  HP 5740 inkjet on Windows XP. I’ve read that others had the same problem so i will try to make a small tutorial on how to solve the issue.

The issue is about the inability of the installer to find a certain file (hpf4ec10.dat) inside itself during the installation process. I’ve tried to find an answer in the HP forums, but it was sketchy at best.

First of all , if you are just looking for the file , it can be found here . Now, if you want to do this yourselves you will need an extractor. I used universal extractor http://legroom.net/software/uniextract . After installing it you will be able to extract manually the files of the driver like that.


If you didn’t have any issues (and probably shouldn’t) you must have a folder of the installer with all the files inside. You will need to find the file in the path “\enu\drivers\com_lang”.


After that you are ready!
