Failed to instantiate CLSID_VirtualBox w/ IVirtualBox, but CLSID_VirtualBox w/ IUnknown works. PSDis

遇到什么问题

Win 7 64 位安装 VirtualBox 5.2.12成功后，安装 ubuntu 失败，报错 VirtualBox COM对象获取失败
Failed to instantiate CLSID_VirtualBox w/ IVirtualBox, but CLSID_VirtualBox w/ IUnknown works. PSDis

解决办法(修改注册表)

进入注册表界面，快捷键win + R 输入 regedit
找到 HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-C000-000000000046} 将 InprocServer32 默认值修改为C:\Windows\system32\oleaut32.dll
HKEY_CLASSES_ROOT\CLSID\{00020424-0000-0000-C000-000000000046} 将 InprocServer32默认值修改为C:\Windows\system32\oleaut32.dll
然后重启计算机，问题解决
