seems Installer screws up when Host Win10 incl. RamDrive like r:\temp will be used.
Error comes up like "File not found". After short investigation i could install 6.0.6 by this:
VirtualBox-6.0.6-130049-Win.exe --path "C:\Users\Josh\Downloads\VirtualBox-6.0.6-130049-Win"
Installer was able to extract .msi File and Installation walks thru smoothly.
VBoxInstallLog will show this when you did not use --path:
