The following error is returned when trying to install netipfw.inf to my network adapter:

"Could not add the requested feature. The error is: 0xE000022F"

What does this mean, and how could I fix it? I am using the latest Dummynet Windows x64 binaries.


  • Those binaries are two years old (before Windows 10). Try building from source. – DavidPostill Apr 16 '16 at 12:19
  • I have compiled Dummynet from the source, but I am now receiving, "the application was unable to start correctly (0xc000007b)." I have the latest .NET Framework, and DirectX installed. – MrTod Sep 19 '16 at 6:32

Install netipfw.inf after disabling signed driver enforcement.
See Windows 10: Disable Signed Driver Enforcement

Click the Start Start menu and select Settings.
Click Update and Security.
Click on Recovery.
Click Restart now under Advanced Startup.
Click Troubleshoot.
Click Advanced options.
Click Startup Settings.
Click on Restart.
On the Startup Settings screen press 7 or F7 to disable driver signature enforcement.
  • can you add some detail and why, etc – mic84 Jul 20 '16 at 8:58
  • I able to install this driver but it does not appear in list of items, – Maxim Shoustin Apr 23 '17 at 13:42

This is probably due to a compatibility problem for NDIS 5.x drivers on Win10. Since microsoft does not seem to fix this issue, instead someone would have to update dummynet to NDIS 6.
