Hello. I'm don't can update VirtualBox from version 4.3.10 to last version.
Installations want file "VirtualBox-4.3.10-r93012-MultiArch_amd64.msi" from folder "C:\users\user\appdata\local\temp\random.tmp\".
But my OS (Windows 7 x64) same time clean temp folders.
PLEASE give me current file.
Or say me how uninstall old version without this file.
THANKS!!!

That is actually a Windows MSI error, not a VirtualBox error. MSI == Microsoft Software Installer.

All you can do is go into Add/Remove programs and try to uninstall/remove the existing VirtualBox application. If all else fails it may be necessary to manually remove all keys from the registry which mention VirtualBox.

Ran into the same issue today... fixed it by going to virtualbox org /wiki/Download_Old_Builds_4_3 and re-downloading the installer for 4.3.10, running the install and doing a repair, then I was able to install 4.3.30

Hope this helps.
