Nvidia driver issues - Can't update the driver?

So, there are problems with my game. It crashes whenever I spawn a Covet. I tried to deactivate some mods to see if one of them might be the cause, but the mod manager performance is lower than ever. It takes a lot of time to load, at high graphics settings it is not operable at all and at low it is barely usable - worse than it used to be at high.
I went on the forum and read about the driver issues, so I thought that should be the cause. I have a Lenovo laptop, Windows 7 64-bit and a Geforce GT 740M card. My driver version is 425.31, I updated it on the 9th of April when I bought Automation.
When I try to install the 430.53, it says that the driver is not compatible with my version of Windows and it couldn't find compatible graphics hardware. I did download the correct version for 8 and 7 (64 bit).
What should I do? Perhaps contact Nvidia support instead? Could they have uploaded a wrong version as the 7-8 one? Or is my problem caused by something else?

 

I am using 425.31 currently, so it's fine actually? The Covet problem turned out to be a mod-related one. The mod manager one...could it have become slower after an update? (Anyway, I have 350+ active mods)
Now what's funny is that I am unable to install even the pre-hotfix 430.39 driver. I should probably contact the Nvidia for this one.

 

I think you can download the drivers from Nvidia and force update yourself to 430.53 to get around the buggy mess of 430.39 that caused the game to crash so much
