When I try to install the latest 64-bit Windows 7 version of the App, with an 8-core AMD processor, 16 GB of memory, and plenty of disk space available + VirtualBox, the VirtualBox installation seems to complete successfully, then the app install starts, but fails when it can't find World Community Grid.msi.

I've never had this problem before. I have the previous version with VirtualBox installed and it gave no problems.

Any ideas why this is happening?

thanks,

Phil

According to your error message, you had BOINC by World Community Grid installed. They have their own client with WCG livery. It's possible you installed VBox separately from that.

When BOINC installs itself, it will check if a previous version of itself or similar is installed and if so, uninstall that previous version, using the Uninstaller of that previous version. And herein lies the problem: Windows tends to forget where it puts these files, resulting in the error message about the missing MSI file.

This can be fixed, see for steps this BOINC FAQ. In this case though you'll want to install the previous World Community Grid BOINC again. Which is probably http://boinc.berkeley.edu/dl/wcg_boinc_7.2.47_windows_intelx86.exe, but do check its version number if you can (old stdoutdae.txt logs in the data directory will show what version you ran last).

Also do know, that if you ran the WCG version of BOINC, that this version is 32bit only. When you now install Berkeley BOINC, and you got the 64bit version, check the installation path for the BOINC programs.

Windows does not allow 64bit programs to be run from the 32bit C:\Program Files (x86)\ directory tree. So if BOINC tries to install its programs to that directory and it's the 64bit version you have, make sure to click Advanced in the 3rd screen in the installer and change the Programs path to the 64bit C:\Program Files\BOINC\ directory.
