[Last check before V3 release]

Usually installing only driver and toolkit works. Possibly QFX 1700 works not well with CUDA with that drivers.

But please check that all what installed has same "bitness" - 64 bit drivers, toolkit and 3D-Coat

or 32-bit drivers, toolkit and 3D-Coat.

But more essential problem is that QuadroFX 1700 will not give good CUDA advantage. Even cheap 9800GT is 3 or 4 times faster them 1700.

1700 has 32 stream processors - see www.nvidia.com/page/qfx_mr.html

9800GT - 112 - http://www.nvidia.com/object/product_geforce_9800gt_us.html

Yes, both of my installations are 64 bit (cudadriver_2.2_vista_64_185.85_general.exe & 3d-Coat-V3-00-03-CUDA64.exe). I need the Quadro card because I'm runing 3D Studio Max and don't have enough cash to upgrade right now, cash will go to 3D Coat IF it can work with my setup. I even tried the suggestion to install an alpha version of 3D Coat but that didn't work either.

I don't know if this is relevant but I found something in the CUDA forums that address some incompatibilities between cudart.dll and Vista 64.

"I found that there is a dll conflict under x64 system: if you try to run x64 app, it fails because it needs x86 version of the cudart.dll, but x64 version exists in the system path."

It seems that CUDA toolkit wasn't installed properly.

Try downloading and installing it again may help.

also you need to update your directX runtime to the latest version

hope this helps.

CUDA installed fine. It shows in my computer that I have CUDA but the file that it refers to is NVCUDA.dll, cudart.dll was not installed. Also Windows Vista 64 bit comes with Direct X 10, Direct X 9 won't install in Vista 64.

Install 3.03 i think the problem was solved, otherwise install an old alpha and copy the file to the new.

I tried 3DCoat 3.03 and still no go. Can you give me more information as to how to install the alpha? Where do I find it? What files I need to copy?

I installed 3d-Coat-V3-00-01-CUDA64.exe and cudadriver_2.2_vista_64_185.85_general.exe. I cannot run 3D Coat. I have a Quadro FX 1700 in my system and have installed Cuda 2.2 but the system cannot find cudart.dll and the program won't start. I do show as having NVCUDA.dll installed though. I'm running Vista Home Premium 64 bit. Can someone help.
