I wanted to run Linux through my Winows 8.1 machine using VirtualBox as hypervisor. After I tried adding Ubuntu (or Fedora, on another instance) to the list of virtual machines, I clicked Start, but it refused to run and an error popped up, saying:
Result Code: E_FAIL (0x80004005)
Component: Machine
Interface: IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}
and another error message was also given, saying:
Error relaunching VirtualBox VM process: 5
Command line: '81954AF5-4D2F-31EB-A142-B7AF187A1C41-suplib-2ndchild--comment Fedora32 --startvm fd699e30-a77b-4eac-8ced-1210d756855d --no-startvm-errormsgbox' (rc=-104)
Although downgrading to VirtualBox 4.3.12 works, so does upgrading to 4.3.16.
I had the exact same problem as user135626 today, probably as a result of a Windows update and a Security configuration change.
When looking for newer versions from INSIDE VirtualBox 4.3.14, I was told that I was running the latest version. Which was incorrect.
Version 4.3.16 is available for download from https://www.virtualbox.org/wiki/Downloads
Possible solution: The following registry key seems to cause trouble:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers] "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe"="DISABLEUSERCALLBACKEXCEPTION"
See if this entry exists. If so, delete it and try again.
You may also need to disable your antivirus. If nothing works, try one of the following:
Also, as a side note, if you are using Windows 8.1 Pro or higher, try Microsoft's Client Hyper-V. I extremely prefer it over VBox.
Look at this https://www.virtualbox.org/ticket/13187Virtualbox 4.3.14 crashes
The solution so far (2014-8-17) seems to be downgrade to 4.3.12 or use 4.3.15 testcase .
