I launch from a desktop icon with the following command: ""C:\Program Files\Oracle\VirtualBox\VirtualBox.exe"" --comment ""Windows 7 x64"" --startvm ""Windows7x64"" --fullscreen Every now and then I get an error message stating: There is no virtual machine named Windows7x64 Could not find a registered machine named 'Windows7x64' Details Result Code: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001) Component: VirtualBox Interface: IVirtualBox {c28be65f-1a8f-43b4-81f1eb60cb516e66} After this occurs, if I launch the VirtualBox gui, I notice that my VM has disappeared and is replaced with two inaccessible vms: debian6 (which it thinks is located at D:\VirtualBox\debian6\debian6.vbox) test (which it thinks is located at D:\VirtualBox\VM\test\test.vbox) My VM is actually located at D:\VirtualMachines\Windows7x64 Every time this occurs I have to clone the VDI and re-build a virtual machine, which causes Windows to need to authenticate again. I have no idea where it's getting this information from as my VirtualBox.xml file has the correct information in it." defect closed other VirtualBox 4.1.14 invalid Windows Windows
