Hello, after installing Windows 7 on an old Dell Precision M6300 which had Windows XP, I have found that nv4_disp.dll which is needed for XP is not working properly with Windows 7. Does anybody know if the Nvidia Quadro FX 1600M has a driver that will work on Windows 7 OS for XP application?
Sorry but did you try to reinstall the Nividia XP driver changing in properties (.exe) selecting that it works under Windows XP SP3 and as an administrator?. I did it with some drivers and it worked fine with w7 32 bits. I think it could be the same thing in your case.
