You just need to delete old configuration file which already "exist"

C:\Users\Gabby22\VirtualBox VMs\CS50 Appliance 2014\CS50 Appliance 2014.vbox'

Open the cs50-appliance .ovf file, you right click and open it with a text editor (I mean , notepad is ok).

Try to go around line 128 and search for that:



try to change it to





It should solve your issue.


Give me a feedback please :) ^___^

Thank you dear,
Actually when the answer wasn't coming in time, I uninstalled every thing and re-downloaded it and it worked fine.

 If you can help with this one I will be grateful: The installation is too slow to my liking, it takes more than 4 hours to give me the desktop and mostly all functions turn to be unresponsive to click.

Please I need help badly.

I can do nothing about it: it's due to your hardware, more likely your RAM :)

What you have to do is to delete old configuration. try also using the .ova and see. i think that one is going to work. wish you all the best. it will work ma man.

just go to the folder where your virtual box/virtual machine has been installed. Delete all the files and folders of that machine. (Don't delete the virtual box software/files from program files etc). Just delete the Virtual machine folder, like the name of the database or whatever the way you named it. The point is to delete the .vbox file which the error said already exists.

Then import that Image .ovf again and it will work. I did the same!

Kind regards!
