Oracle VM VirtualBox 5.1.14 安装完成之后显示错误, Failed to instantiate CLSID_VirtualBox w/ IVirtualBox, but CLSID_VirtualBox w/ IUnknown works.
原因是注册表错误, 修改注册表:
Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-C000-000000000046}\InprocServer32] @="c:\\windows\\System32\\oleaut32.dll" "ThreadingModel"="Both"
