many validation errors after clean installation

You can get SFEP.sys from a newer model. All models use the same driver for that device, so even though the driver comes from a newer model, it should work on your system. Sony® Firmware Extension Parser Device Driver

That may resolve the errors you are having, as well. Post back whether it does.

the link you have posted says "Applicable Products and Operating Systems (see full list...): Model:
VPCEH290X
Operating System:
Windows® 7 64-bit

but my windows 7 is 32 bit, i guess it wont work for me

Yes, that driver will work for you. I did the same thing with my VPCCW17FX: https://www.sevenforums.com/crashes-d...sony-vaio.html

I used the exact same driver I linked to for you. It does not list the VPCCW17FX, but the driver still worked and solved my issues. As I said in my previous post, the SFEP.sys driver is the same FOR ALL MODELS.

it is said to be incompatible by windows

Odd. Sony : VGN-FZ11Z updates | Download updates for VGN-FZ11Z may help. The Sony Firmware Extension Parser should be included in that.

NOTE: you may have to install drivers in compatibility mode as in Drivers - Install Vista Drivers on Windows 7
