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)
I am running Windows 7 and that particular Registry Key does not exist. I have gone back to version 4.3.12 and it is working fine. – None – 2014-07-20T13:41:53.037
1It was the antivirus (avg) that was causing the problem for me. Thank you! – brettville – 2014-07-24T03:25:18.593
1You're welcome. Realize I do NOT recommend uninstalling/disabling your antivirus, rather downgrading VBox or using Hyper-V instead. – Duncan X Simpson – 2014-07-24T03:36:17.090
Wonder, how much is the cost of Hyper-V. This is the second time I had to go through this hassle.. – alpha_989 – 2018-02-16T04:01:56.310
