I cannot import appliance50-19-vbox.ova to VirtualBox. I get this error message:

Failed to import appliance C:\Users\Rumid\Downloads\appliance50-19-vbox.ova.

Could not create the clone medium 'C:\Users\Rumid\VirtualBox VMs\CS50 Appliance 19_1\appliance50-19-0-vbox-disk1.vmdk'.

VMDK: Compressed image is corrupted 'C:\Users\Rumid\appliance50-19-0-vbox-disk1.vmdk' (VERR_ZIP_CORRUPTED).

  • Did you try using VMware player?

Did you try VMWare Player? It is free and is much easier to use. Check this article.

  • Alternatively you can try re-downloading the .ova file - it might be broken. Commented Jul 1, 2014 at 18:11
  • Thanks, it's worked :)

I faced the same exact issue, you can try going to

c/users/<your username> 

and deleting .virtualbox and virtualbox VMs. If it didn't work, I am afraid that you have to uninstall oracle virtualbox and check that it deleted all files.

You can go to

 c/program files/ 

and delete the oracle folder then restart your computer and install it again.

  • Going to Program Files and deleting the Oracle folder is not the typical way to uninstall VirtualBox!
