Windows 10 64 - How to get IT working?

So i have got some people who would like to play IT with an Win 10 x64 PC or Laptop.
However, i myself cant get IT to run on my Win 10 x64 Surface so i cant help them, but they get the same error.

OIS.dll is missing. But the file is in the game folder.
All the tutorials i found to register that .dll file lead to errors telling me that its not working.

Anyone any idea how to get IT games running on Win 10 pro x64 devices?

My client and my game project is working perfectly under Windows 10 x64 with the latest build/updates installed.. that's strange, that it isn't working for you..

Have you tried to rebuild your game?

I noticed i have win 10 pro, maybe its important to know?
However, the game works perfect on win7 and i have no problems there. So its not the build, i used the game installer from my download, no source on this laptop/surface device, so it should work.

I tried registering the .dll file with a tutorial but even then it says the file cant be found when its right inside the folder that i correctly wrote into the cmd to load it up.

I tried deinstalling the ois.dll in case, but the system says it is not installed/registered.

I am running Windows 10 X64Bit Home without a problem with Dragon's Den.
Also the game is compiled on that computer no problems.
Maybe it's a hardware issue.

I have got it to work!
After getting some missing .dll files and installing direct3d9 rendering system, everything works as it should!
