It's so strange that we have never encountered this situation before. We've analyzed the log file and the program prompts the following error message:
VBoxManage.exe: error: Cannot open the raw disk '\\.\PhysicalDrive4': VERR_SHARING_VIOLATION
VBoxManage.exe: error: The raw disk vmdk file was not created
This usually means that there are other programs using this disk, do you confirm that no other program or another virtual machine is using it? Can you try it on another computer to see if it works? Or can you set the save path for the virtual machines as the default path?
