Hello Apertis, I am trying to build an app for apertis but are facing certain problems that I have explained below. Has any of you faced any such issues? Problem 1: I get the following error when I select the Add guest additions CD image in Virtual Box: Unable to insert the virtual optical disk C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso into the machine Apertis. Could not mount the media/drive 'C:\Program Files\Oracle\VirtualBox/VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED). Result Code: E_FAIL (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed} Callee: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0} Have you encountered this problem? If so could you kindly help me resolve it? Problem 2: When I start eclipse, I do not see the Project Wizard Button. Is this problem associated with Problem 1?
