I'm getting the following:

The installer failed with exit code 667: VBoxExtPackHelperApp: error: Failed to open the extension pack tarbalVERR_ACCESS_DENIED ('/Users/joeclifton/Downloads/Oracle_VM_VirtualBox_Extension_Pack-6.0.8.vbox-extpack')
rcExit=1.

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ExtPackManagerWrap
Interface: IExtPackManager {70401eef-c8e9-466b-9660-45cb3e9979e4}

Any help would be appreciated.

How exactly are you trying to install the ExtPack, by double-clicking on it? As which user, "joeclifton"? Can you post the output of the command (run from the Terminal):

• 
  ls -ale@ /Users/joeclifton/Downloads/Oracle_VM_VirtualBox_Extension_Pack-6.0.8.vbox-extpack

There's another way to install the ExtPack, by going to the VirtualBox Preferences » Extensions » click on the folder icon with the green plus () and navigate to where you stored the ExtPack. You'll be prompted for an admin username/password.

Yes i try by double-clicking on it.
i tried the way in preferences and get the same error.
here is the output of the command:

Joes-MBP:~ joeclifton$ ls -ale@ /Users/joeclifton/Downloads/Oracle_VM_VirtualBox_Extension_Pack-6.0.8.vbox-extpack

Issue the command:

• 
  xattr -rc /Users/joeclifton/Downloads/Oracle_VM_VirtualBox_Extension_Pack-6.0.8.vbox-extpack

Move the ExtPack to somewhere common, like /Users/Shared/Downloads. Then from the Finder » Get Info, give everyone read-write access.

Really don't know why it does that, here's how the equivalent mine looks like, and I've never had a single issue:

$ ls -ale@ /Users/Shared/VirtualBox/_Downloads/6.0.x/Oracle_VM_VirtualBox_Extension_Pack-6.0.8-130520.vbox-extpack

What version of OS X are you running? There has been a report recently of Catalina betas not allowing installation from the regular download directory.

D'oh!
I completely forgot about that (MacOS Catalina 10.15 Extension Pack Fails)! Thanks Andy!

Oh, and if you want to really start crying about VirtualBox not working at all in Catalina and later, check out "7 Big Security Surprises Coming to macOS 10.15 Catalina". After I read it, I wanted to submit the author in a flogging ritual for dismissing like it's no biggie, the elimination of kexts...

Forgot to tell you that it was Catalina Beta ...
\I moved the pack to another directory and it installs fine now.
Thanks for all the help.

Great, thanks for the feedback. Marking as [Resolved].

Moving to "OSX pre-releases" from "OSX Hosts".

In Vbox, I went to:

Preferences > Ports > USB > USB 1.1 Controller

And VM runs.

I had created a partitioned drive strictly for my OS emulator and had the extension file placed on that drive. I would get this error when the extension was located there. Thanks to this post, I had to move it to a common area on my main C: drive for it to work.
