Win7 64bit: Error sending IRP to driver

[jabex]

I try to use it in a win 7 64 bit installation with Driver Signing check and Patchguard disabled.

When I try to hide a process I obtain this output:

I have compiled the driver in Visual Studio 2017 runned in Win10, and I checked the follow option:

• Driver Setting:
  Target OS Version = Windows 7
  Target Platform = Desktop
  Platform = x64

• Configuration Manager
  Active Solution Platform = x64
  Platform = x64

About the loader, have compiled it use the command "make 64bit"

Thanks
