CreateTexture2D fails for GeForce GTX 280 user

Seasonal greetings,

My game uses MonoGame for Windows desktop and one Windows 7 user gets an error every time when creating a 2D rendertarget:

HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect.

Line: 0

at SharpDX.Result.CheckError()
at SharpDX.Direct3D11.Device.CreateTexture2D(Texture2DDescription& descRef, DataBox[] initialDataRef, Texture2D texture2DOut)
at Microsoft.Xna.Framework.Graphics.Texture2D.CreateTexture()
at Microsoft.Xna.Framework.Graphics.RenderTarget2D.GenerateIfRequired()

The user has Win7 SP1 and also this patch:

https://support.microsoft.com/da-dk/kb/2670838

which is supposed to help, but doesn't.

I found the patch in this thread: https://steamcommunity.com/app/498240/discussions/0/360671352681600886/

Chip type: GeForce GTX 280

Any ideas??
