I have verified that the MD5 checksum for the extension pack matches the one published on your website.

I did verify that it seems to be actually creating the temporary directory (I did this by opening the ExtensionPacks subdirectory in Windows Explorer and visually watching it as I attempted the installation - a new folder appeared briefly then disappeared again followed immediately by the appearance of the error dialog).

I searched the forums for anyone else experiencing the error - I did find someone else and their error appeared to be identical to mine but, in their case, they have VBox loaded on a Windows XP host, so UAC seems an unlikely contributor. ( NOTE: My boot drive (C:) is a small solid-state drive so I have the user account directories on my G: drive and install most software there as well.)Īs the error suggests "access denied" and the host is Windows 7, I immediately suspected UAC, however, I am not so sure of that now. The installer failed with exit code 1: VBo圎xtPackHelperApp.exe: error: Failed to rename the temporary directory to the final one: VERR_ACCESS_DENIED('G:\PROGRA~3\Oracle\VIRTUA~1/ExtensionPacks/Oracle_VM_VirtualBox_Extension_pack-_-inst-4100' -> 'G:\PROGRA~3\Oracle\VIRTUA~1/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack')Ī screencap of the error dialog is attached. I installed VirtualBox 4.0.0 onto Windows 7 Professional and attempted to install the extension pack: Oracle_VM_VirtualBox_Extension_Pack-4.0.0-69151.vbox-extpack I have attempted the installation both without and with VMs running. Latest Version: VirtualBox 6.1.Note: I have not attached a session log file as attempting to install an extension pack, predictably, does not appear to generate anything in the session log for a VM.
