I've read around all the fixes - reinstalled the .Net Runtimes, instaled Wintab, which enabled PaintShopPro pressure senstivity, and even signed up to Adobe and installed the PS CC demo. Nothing enables pressure sensitivity on my SP4 with Krita 3. Is there anything else I can do? Why would it work on some SP4s and not others when the hardware is identical?

I don't know: I guess you have to ask Microsoft.

Make sure you get all of the windows 10 updates. it takes quite a few hours, but that seems to fix things. That and installing the wintab drivers seemed to do the fix for me.

hi there!
same problem here: tried all the suggested things. Photoshop trail is working perfectly, so does Mischief. But no way to get Krita to work. I also checked for updates, but it says that it is already everything updated.

I hope someone will solve it and post it here!

I hope someone will complain to Microsoft and make them fix their stuff, since Krita is perfectly wintab-spec compliant: if a wintab-driver enabled piece of hardware gives trouble, it's the driver that is buggy!

I solved the issue just now. In the order:
1) I deactived the open GL from Krita setting. Closed Krita.
2) I downloaded the wintab drivers. this time the 64 version
3) I reinstalled (by "repair") the drivers (the 64)

I opened Krita again, with no hope, but this time it worked. I start to believe that what made it work, was the "no hope" bit ;P

Jokes aside, let me know if it works for you. I did try so many other things before this last few steps, and they may have affected the final outcome. If these steps do not work for you, I will try to least other things I tried.

Good luck!

Even the eraser on the back of the pen works!!!

I am so happy now!

And that's when people tell me you need the 32 bits drivers... There is something totally non-deterministic here.
