Greetings:

I'm running Windows 8.1 on a Toshiba "Satellite" C-75D-B laptop computer, with a AMD A8-6410 APU with AMD Radeon R5 graphics 2.00 GHz processor, with 8 GB RAM (6.96 GB usable), 64-bit operating system, x64-based processor.

My BOINC projects include SETI, World Community Grid, SZTAKI, Milky Way, Rosetta, LHC, Einstein, and POEM.

On April Fool's Day, Wednesday 01 April 2015, I downloaded and installed the latest version of BOINC, 7.4.42 Windows x86 64 Virtual Box.

It would not connect to the Internet, although I couldn't figure that out until this morning, Saturday 04 April 2015.

So, I did a system restoration to April Fool's Day, Wednesday 01 April 2015, and then downloaded and installed the updated version of BOINC, 7.4.36, which comes WITHOUT Virtual Box, and after installation, my BOINC program immediately connected to the Internet.

PROBLEM SOLVED ! ! !

Thank you.

Virtualbox includes some networking drivers it installs to handle communications with the VM. Its possible they didn't set up properly and messed up something.

Unless you need to run a project that uses Vbox I'd suggest you stick with the vanilla version of BOINC.
