Hi there,
TW installed fine with the Physx drivers, after i removed the previous Physx installtion. But the game crashes with the very uninformative error message "Two Worlds has stopped working". Installing the latest Physx drivers from Nvidia hasnt helped much. Any ideas? Thnx in advance
I'm using Windows 7/64 on an AMD Phenom II X4 940 and a Nvidia 9800 GTX+ with latest drivers.

Try running as Administrator and set compatibility for Windows XP (SP3) (listed in in option 3 in the following thread)

If you still have problems try different compatibility settings.

Sry, doesnt help at all. I tried the un-official "TW control pad", tweaked around a little, but wasnt successful neither.

I had a similar problem when I installed the game. The installer quit when it got to the Physx install bit. I did not try to install it later as I was already up to date.
When I first tried to play the game it froze on the screen where you had to enter your name. I rebooted and started in safe mode. It started in a very small window. I was now able to enter my name in and start the game. Pressing escape and options I selected a higher video mode, but kept windowed mode selected as I find I have less problems over all if I olay games windowed.
After quiting the game then started fine in normal mode with the previously selected video resolution.
This may help someone else with a similar problem

I'm getting the same thing. I'm using windows vista, but i have an nvidia 9800 gtx as well, coincidence?

Maybe a hardware/driver version thing ... does renaming/deleting this specific DLL help?

I'm on Vistax64 with a 9800gt. In the installation when it came to the PhysX install I cancelled it and just used what I have. I didn't have a crash. (just throwing that in there). Also not using quite the latest drivers, although they're downloaded for installation. Since it works with TW I may just leave well enough alone.

The nVidia autoupdate util seems to want to install 32 bit drivers on a 64 bit system by default. I have the same crash problem as well after running updates (including nVidia driver updates from the nVidia control panel). I'm just trying a manual update of the whole nVidia bundle from the website to see if this fixes the issue. Renaming the dll didn't help in my case.

Hi everyone,
I was able to fix the problem. In my case the described deletion/renaming of "Physxloader.dll" didn't work. I had to deinstall the latest Nvidia PhysX component and install the older version 9.12.0613 instead. Now everything works fine.
Note that I copied the "Physxloader.dll" back in the folder after the mentioned method didn't work.

I hope this information helps you out.

Greetings from Germany.

For a permanent fix without any workarounds, simply install the NVIDIA PhysX Legacy System Software. This version can be used alongside the latest normal NVIDIA PhysX System Software version without any tinkering (newer PhysX versions won't replace the Legacy files Two Worlds needs).

This is the best solution, just had the problem on my laptop and found the legacy software installer on Google. They should really repackage the two worlds installer with the legacy system software.

Thank you very much.

Mine came up with no error message, just crashed. I tried the download you suggested and it now works.

Arkose's solution is the best. Works great.
