Error in Standard Shader, too many instructions, on Windows 64

Error message is

Shader error in ‘Standard’: Too many
math instructions for SM2.0 (65
needed, max is 64)

This also occurs for Standard (Specular) as well. It is occurring on a colleagues machine as well. We are both using 2017.1.0p4.

Any help with this would be greatly appreciated.

this is cos your machine’s video card / hardware cannot fit the shader into its small cache.
The solutions would be… use simpler shaders, or update your video card.
obviously buying video cards is expensive.
So try not using the standard shader (which tries to do everything in one )
try selecting legacy, or mobile shaders… Which are simpler, with less instruction sets, generally render faster also… but you lost some of the nicer phyically based rendering and lighting. (which doesn’t really matter if you are making mobile or 2D game)

Note SM2.0 means shader model 2.0 which is pretty old hardware by today’s standards…

@JonPQ It can’t be a video card upgrade. I have a GTX 1080 Ti and have the same error.
