Error message - Portable VirtualBox on USB stick via LiLi

[GeTh]

Greetings,

I have just installed Linux Mint 17.2 on USB Flash Drive with Portable VirtualBox via Linux Live Creator.
Alas while starting the system from the drive (Virtualize_This_Key.exe or VirtualBox.exe on the drive) I have the following error message:

Failed to open a session for the virtual machine LinuxLive.
Failed to open image: 'F:\VirtualBox\Portable=VirtualBox\data\.VirtualBox\Machines\LinuxLive\HardDisks\LinuxLive.vmdk'
for writing due to wrong permissions (VERR_VD+IMAGE_READ_ONLT).

Failed to arttach driver below us! Image is read-only. (VERR_VD_IMAGE_READ_ONLY).

Details:

Result Code:
E_FAIL (0x80004005)
Component:
Console
Interface:
IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

I have changed all files attributes in the VirtualBox folder on USB drive to NOT Read Only.
I will be deeply thankful for any helpful assistance.
Thank you in advance.

We do not support 3rd party apps like portable virtualbox. You need to ask them for support.
