When I try to install the new Seti + Virtual Box it hangs the computer when I respond "yes" to the question about do I want to allow the (vbox?) driver install - the screen, mouse, and keyboard lock up. The Registry and system are clean before install.
If I delete my old Seti Ver 7.2.42(X64) and vbox and try to install from the new downloaded file, the same happens.
If I just delete Seti and vbox, the MS Internet Explorer locks up. Google Chrome still works, however. It appears that Seti or vbox application delete damages something in MS Explorer.
Computer: ASUS 990FX/GEN3 R2 MB, AMD FX8370E cpu, 16Gig main memory, Sapphire HD 7970 graphics, Samsung 830 SSD and screen, Windows 7 64bit.
I can run fine with the old Seti Ver 7.2.42 + vbox, so the heat is off temporarily. It appears I may have to reinstall win 7 to get rid of the problem.

First question I would ask, are you running any other projects that require the virtual box?

If not, then try installing Boinc without Virtual Box and see if it completes.

my 2 cents

I would expect it is VirtualBox being disagreeable on your system. On one of my server I use VirtualBox and has to roll back to an older version, 4.3.14, because the most recent version at that time was a bit broken.

That is a problem with the Virtual Box driver and most Anti virus softwares with system manipulation protection. VBox tries to modify the virtualization layer of the operating system and the AV software denies access, so the install crashes and most of the time leaves the system in an unusable state. Look at the forums of Virtual Box. Only the older versions from ~March/April are working.
