I was just wondering if it would be possible to install the CUDA toolkit without replacing my Display Driver. I don't mind the other changes that the installation would make to my system, but wish to keep my current NVIDIA display driver, rather than change to the one in the CUDA installation. Therefore, is this possible, or is the replacement display driver required to develop and run cuda programmes?
You need a display driver that is at least as recent as that included in the CUDA toolkit that you are installing. For example, Linux CUDA 5.5 requires a 319.37 or newer display driver, Linux CUDA 5.0 requires a 304.54 or newer display driver.
During the install of the toolkit, you will be prompted as to which components you want to install (driver, toolkit, samples). You can select no when prompted for the driver, if you wish to keep your driver. There are getting started guides for each of the supported platforms (windows, linux, mac).

Could someone help me with the process of downloading opencl 1.2 on windows 10 with Nvidia geforce gtx 1050?
I downloaded the latest version of my nvidia graphics card, but when I look into its folders its shows an empty folder for openCL.
Should I be downloading any sdk's for nvidia? If yes where can I find it? I am able to find the nvidia openCL page here https://developer.nvidia.com/opencl but not sure which one to select
The OpenCL 1.2 runtime is already included in the graphics driver. There is no need to download any other software. You don't need any SDK.
For OpenCL development you will only need the OpenCL header files, see this post here.

I have multiple machines that do not have openGL capable graphics controllers (or at least not for the OS I am using), and I am trying to run various softwares which require openGL32.dll to be present and working. I only need openGL version 1.4 compatibility.
My question: Is there some sort of software-only emulation for openGL that I can use to run these? I have heard of MESA, but all I need is the dll, and MESA seems to require that I build everything manually.
I am running Windows 10 x86_64
I'm pretty surprised that a machine running Windows 10 does not have a GPU capable of supporting OpenGL-1.4 – most likely you simply don't have the proper drivers installed and that's all your troubles. OpenGL dates back almost 15 years; that was before shaders where are thing.
The default Windows installation does not ship with fully featured OpenGL drivers, because Microsoft in all their wisdom decided, that they'd strip perfectly working OpenGL drivers from the drivers installed through Windows automatic driver installation.
To get full and proper OpenGL support you absolutely must download the drivers directly from your GPU vendors website and install those. Open up the "Hardware Manager", look for "Graphics adapter", there you find the name of it. Type the name plus "driver Windows" into the little box of Google and it will carry you to the right place.
Mesa3D seems to publish its own versions of it: https://fdossena.com/?p=mesa/index.frag

Last week my graphic card Nvidia (Cuda 2.0) stopped working and I had to plug in an old one which only supports Cuda 1.1. I have the NVidia Cuda 5.0 Toolkit installed. The project still compiles, but I get a runtime error. Therefore, my question is: do I have to reinstall Cuda again or change other settings in the cuda toolkit if I change the graphic card?
CUDA sdk is the same whatever your NVIDIA card but you should need to install the right driver. But you might change some settings in the code..

I am new to OpenGL. I have to develop a simple 3D application. I read from Google that I have to install GLUT and OpenGL. Is that right? Can you tell what exactly should I install?
Any link for proper download is appreciated.
Google that I have to install GLUT and
You don't need GLUT necessarily. A lot of tutorials use it, though.
OpenGL. Is that right?
Well, OpenGL is mostly an API to the drivers. So what you actually need are the drivers for your graphics processor directly from the vendor. The drivers Windows7 installs automatically lack modern OpenGL support.
So just head over to http://intel.com or http://amd.com or http://nvidia.com, depending on your GPU, and download the drivers for from their site directly and install them.
What I highly recommend is getting GLEW: http://glew.sf.net – it makes things to much easier in the long run. Especially if you want to do anything beyond OpenGL-1.1 you'll have to use the so called extension system which is a bit tedious to use directly. GLEW hides this all behind a single function call to glewInit(), once you've got a OpenGL context.

Is is possible to do Open GL development and run programs on a computer with out a graphics card? (e.g. my netbook running Ubuntu)
Update This was many years ago, the link is not available anymore, and there are probably newer, better, builds now.
Yes, you can use MESA.
For your convenience, I've compiled it in both 32- and 64bit at:
http://dl.dropbox.com/u/9496269/mesa.zip
Simply put them where your executable file is located.
Sure. Many software only implementations of OpenGL exist. Check out the Mesa project at http://www.mesa3d.org/ for one of the most popular. There are parts of the shading language not fully supported, and it tends to lag the standard a bit in general, but that is the case of all software API emulators. Its still very full featured and can be used in production code for many common uses.
You can use OpenGL on many integrated GPUs, mostly AMD chips like the Ryzen 3 3200G, which has a GPU that is the same as a GTX 1050 for around £100.
