I've got big troubles after it has been installed the virtual machine asked early in this program. My notebook:

  • Asus x45c
  • Intel Core i3 2.2GHz
  • 4 GB RAM
  • Windows 8.1
  • AVG Antivirus 2015
  • Keyboard Portuguese Brazil ABNT2

broken down in totally schizophrenic way just after it has been installed from the sources indicated by the links on your web site.

I've followed step by step the prescribed instructions, but stranger behavior have early started in my machine. First the virtual machine keyboard started changing some actions like '4' instead 'p', '6' instead 'u', etc.

Then the app 'Narrator' from Windows started without reason and the 'Word Office 365' started to change the letters too. I tried to uninstall the virtual machine and to do a back up, but I guess that was too late.

When I restarted my notebook I just could use my password by a virtual keyboard, and then came the worst. My notebook as a whole was totally schizophrenic, and I lost all my files, R programming data sets (R Studio), all the stuff that I've gathered to apply for a Health Information Graduate Program included, etc.

Windows automatically creates system restore points that allow you to revert to the state of the system software before you installed VMware (or VirtualBox). See the instructions here for restoring your PC to an earlier point in time: http://windows.microsoft.com/en-us/windows-8/restore-refresh-reset-pc

Of course, as you say, the time to enable a similar automatic backup for your personal files would have been before creating them. Windows 8.1 has a new File History component that makes it very easy to back up personal data: http://windows.microsoft.com/en-us/windows-8/set-drive-file-history

VMware and Oracle are highly regarded software creators, whose virtualization products provide extremely strong protection against corruption of a host computer by a guest virtual machine. Since its release a year ago, hundreds, if not thousands, of CS50 students have used version 2014 of the CS50 Appliance without problems of the sort you describe. It's hard to imagine how the CS50 staff could have provided better safeguards against harm to your computer or data than by using such well-respected industrial tools.

  • I know Oracle and I've installed VirtualBox without trouble, but that VMware I really don't know. I'm not comfortable enough to try to install it again. I've recovered some files that were in the Google Drive and OneDrive. I believe you should do some tests in this VMware. I would have done if I had a patient starting to show such strange behavior.
