Cannot start VMs in Windows 10 x64

Reported by: dburke3 Owned by:
Component: VM control Version: VirtualBox 5.1.8
Keywords: Cc:
Guest type: all Host type: Windows


After initial install of virtual box I was able to create and run a red hat VM. After a restart of the PC, I was not able to start the red hat VM, nor any others (I tried creating Ubuntu and Win7 VMs as a test). When attempting to start one, the following error occurs:

"supR3HardenedDllNotificationCallback: NtCreateFile failed on 'C:\windows\System32\umppc4702.dll' / '\??\C:windows/System32\umppc4702.dll': 0xc0000034 (rc=-225) Please try reinstalling Virtual Box. where: supR3HardenedWinCheckChild what: 5 VERR-INTERNAL_ERROR (-225) - Internal error - this should never happen."

Reinstalling virtual box/restarting the PC had no impact. Running as administrator had no impact. Both 5.1.8 and the 5.1.9 test build exhibit the same issue. Host is Windows 10 Enterprise 64 bit.

I was able to work around the issue by manually creating a dummy file (I just created a text file and changed the extension) 'umppc4702.dll' for the dll that it is failing to create and dropping it in my System32 folder. After that the VM seems to run without issue.

Do you happen to have CrowdStrike? Take a look at: . There is a case open with them from what another user said.
