Brand new windows user here. I have successfully installed Virtual Box 5.1.8, and I'm having trouble downloading the extension pack. This is on a completely brand new machine with windows 10 installed (some sort of HP laptop that I grabbed from Sam's Club on Wednesday). I downloaded the extension pack from this page. I am the only user on the machine and I believe I have administrator privileges.
I run the extension pack (called Oracle_VM_VirtualBox_Extension_Pack-5.1.8-111374
) by double clicking on the icon from the Downloads folder, and it seems to open up Virtual Box automatically and it prompts me with a prompt, asking me whether I want to install the extension pack or cancel. I click install, agree to the VirtualBox license, and I'm met with this error:
Failed to install the Extension Pack
C:/Users/Nick/Downloads/Oracle_VM_VirtualBox_Extension_Pack-5.1.8-111374.vbox-extpack.
The installer failed with exit code 1: VBoxExtPackHelperApp.exe: error: Failed to rename
the temporary directory to the final one: VERR_ACCESS_DENIED
('C:\Program Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack-_-
inst-12020' ->
'C:\Program Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack')
rcExit=1.
Result Code: E_FAIL (0x80004005)
Component: ExtPackManagerWrap
Interface: IExtPackManager {edba9d10-45d8-b440-1712-46ac0c9bc4c5}
So, there seems to be some sort of permissions issue. But I'm confused by the fact that I am the only user on this machine and I am an administrator, so there should be no issue. Secondly, no such temporary directory exists when I look after the failed install, so either there is some sort of automatic cleanup on error or there is a previous error of not creating the temporary folder in the first place not being caught by the install process (might also be a permissions error).
I will update this post with other attempts to solve the problem. Thanks for the help!
You cam manually install the extension pack if the double click and selecting 'Install' fails. From in the app, choose File –> Preferences in menu, then select Extensions option in VirtualBox console. From here you can browse the downloaded extension pack and install it on Windows 10.
