Windows 10: Virtualbox extension won't install

I created a virtual machine and in the process created a user account that has administrator privileges. I then downloaded an extension to virtualbox 6.0.10 and tried to install it from that account, but, get the error "Exit code 1 membership in the administrator's group is required to perform this action". I then searched for this error message and found that the proposed solution was to run the virtualbox manager as administrator. When I do that and then click on the virtualbox machine definition icon I get the error "Fatal: Could not read from the boot medium! System halted." I'm a rookie at this virtual machine stuff as I just created the machine yesterday afternoon. Any help on this problem is greatly appreciated.

Sun VirtualBox

Been there and done that. Followed through enabling the 3D acceleration and as told i hit the "Install Guest Addition" to install the drivers in the guest operating system, after that i was told to reboot the VirtualBox and came to the blue windows XP shutdown screen... It was on that screen for more then 30mins and so i force a shutdown on the original Win7 OS to et rid of the VirtualBox OS shutdown screen. Rebooted and tested VirtualBox with the game and got the same error message as shown in my first post.

EDIT: Gone through all the steps till i came to rebooting the VirtualBox OS. After the system coming up normally, i checked if the 3D acceleration is enabled by running dxdiag. Here is what i get...





Need advise to fix 3D acceleration so i can go on. Thank you so much!
