Ye, i did that, also driver sweeper, but i have no idea why the installer says may Vista is not 64 bit... gonan download from this link too, lets see what happens, thanks.
Thanks buddy, i will try like this too, never deleted anything manually from C:/Nvidia folder, just uninstalled, and after used Driver sweeper in safe mode, after this i could install the .83 it seemed at least, it went thorugh the whole installation process without those stupid 32/64 bit failure messages at the beginning, but at the end when just the: finished, pc restart needed message was expected, instead it gave a message like: system was not modified, if you wish to install this software later run the setup.... bugger....
I will try your proposals, thanks for them.
Ok, with the separate Physix installation i could get it done finally, thanks again Ramon
Results in 3DMark06 did not change, same 13100 as with 177.79
3DMark Vantage went up from 9600 to 11700, nice
Ingame fps also imporved slightly, at around 5% i would say.
Solution:
Restart PC first to make sure no current installer is running.
Run the NVidia .83 driver installation and also open the task manager on the process tab.
During the installation you will notice the 'PhysX_8.08.01_SystemSoftware.exe' process starting. Just END this task. The NVidia driver installation will now continue and it will be installed with a normal finished message.
Then just manually start the physic part:
c:\NVIDIA\WinVista64\177.83\IS\PhysX_8.08.01_SystemSoftware.exe
The driver(s) are now correctly installed.
