Mass Effect 2

Mass Effect 2

Need help getting ME2 to start
Support from EA has been overall pretty useless, so I'll turn to third party support

When I try to start ME2, it says "Failed to initialize the physics system. Please ensure you have an updated version of the PhysX System Software installed."

Okay, so I tried to validate my files, nothing happened, steam seems to think I have everything, alright then, I went to the game files to the redist folder, to the PhysX installer it has there, tried running that

It says the version of PhysX I have right now is too high, so it doesn't do anything

Can anyone help me figure out how to convince ME2 that it does indeed have the software it needs? I'm running Windows 7 64 bit with an AMD Radeon HD 7660D on an AMD A10-5800K APU with Radeon(tm) HD Graphics

The program is being run in compatibility for Windows XP and being run as an administrator, didn't fix anything

I had this very problem after installing ME3. Even uninstalling PhysX and installing an earlier version didn't work.

What did work for me was to completely uninstall PhysX and then go and run ME2. ME2 recognised that I had no PhysX at all on my computer and installed the 'right' version for it to run. I was able to play ME2 fine after that.

(Yes, this does mean if you have any other games that use PhysX -- like ME3 -- if this solution works for you you will need to do this dance every time you switch between the game with the newer PhysX version and ME2.)
I have both PhysX system software 9.13.xxxx plus physx LEGACY drivers from http://www.nvidia.com/object/physx-9.13.0604-legacy-driver.html
and the game runs fine without juggling installations.

That worked great for me. Had to update my PhysX software to 9.13.xxxx so with that and the PhysX-Legacy I don't have to juggle PhysX versions. Much appreciated :)

Thanks very much JCDenton - updating the main physx driver and downloading the legacy driver worked like a charm

can't get mass effect 2 or 3 to work because of physx. i have tried uninstall software and installing it again. i have amd radeon r7 200 series Graphics card. i tried installing the physx software that was in the mass effect 2 folders, that also failed. i have tried compatebility, and run as administrator.

Thank goodness these forums exist! Besides ME2, I also had to look up how to fix Borderlands...

Anyway, long story short, ME2 was working for me fine in the past. Tried playing it today, and that message popped up. Deleted the PhysX file in the ME2 folder and installed the PhysX (Legacy) file. It's working now. Thanks everyone!

I went to start Mass Effect 2 today and the Origin launcher did a 91mb update. Subsequently, Mass Effect 2 failed to start with the error "Phys-X failed to initialise blah blah". This seems wrong as I have an AMD card, what the hell do I need an Nvidia driver for? Still, had a look round the internet and discovered it is installed as "Nvidia Phys-X". Uninstalled it and reinstalled it from the .msi file found at

c:program files (x86)/Origin Games/Mass Effect 2/_installer/physx/redist

Game runs fine now.

Thanks bro!!

I also left the same error, PhysX System Software, with this link've solved you. Although in the nvidia page does not come win10 as recognized system, it works.

My system: AMD FX-8350, x64, 16 Gb RAM, GTX-960 G1, Win10
