I was using Unity 4.2 Free for my project. Today I’ve downloaded new version of Unity. When I try to open my project, I see a popup says the title. I know exactly what does it mean so don’t tell me that I need a new graphic card 
Do I have to install v4.2 to use Unity on my netbook?

1Sadly, you will need either a new graphics card or stick with unity 4.2.2. Be aware though, that you will most likely not be able to play new games that people make from now on.
http://unity3d.com/unity/whats-new/unity-4.3 has this release note.
“Graphics: Removed support for pre-DX9 GPUs on PC. That is, GPUs made before 2003 (NVIDIA), 2002 (AMD) and 2004 (Intel) will not be supported now.”

labeled as unsupported by Unity.
Andy, I think you're telling it wrong now... DX9 supports shader 2.0. DX9c supports shader 3.0. This would mean that the cards you named should be supported. (pre-DX9 is DX8 and older...) When you look at the compile options in Unity 4.3 you also see that you can toggle shader 2.0 and shader 3.0 compilation. Why allow 2.0 shader compilation when you don't support it anymore?
– Reizla@Reizla I quoted the exact statement from the release notes. This would make a nice forum post to attract the attention of someone who works at Unity.
– AndyMartin458Unity 4.2.2 was supposed to work in older GPUs, I just downloaded Unity 4.2.2 for my older Desktop which has 82845, it gives the same error though.

My laptop was purchased new at the end of 2007 and was a current Gateway model at the time. At startup of 4.3 I'm getting the message: Graphics card not supported by Unity DirectX9 GPU (Shader Model 2.0) is required. Your GPU (Mobile Intel(R) 945 Express Chipset Family) ony supports Shader Model 2.0. (Yes, it did repeat 2.0 in the message above.) According to dxdiag the laptop running DirectX 9.0c. Any advice?
– chelmsford123@chelmsford123 I would post a new question asking if your integrated graphics chipset is supported. It seems like their new restrictions might be even more restrictive than DX9 support.
– AndyMartin458I am having the same issue with the webplayer, 4.2 was working fine... now I would like to go back to 4.2 but where can I find it!! there is only an option to download the 4.3.1 but there is no older installers. Any ideas?
