I have had Win10 tech preview running perfectly well on a VMWare Player virtual machine with 60GB HD, 2 processors and 2GB of RAM. Now I get a prompt "Install a new build of Windows now". I am warned that my PC will restart every few hours. When I click on "More info" I'm directed to the MS website to a download link for the file "Windows10TechnicalPreview.exe". When I run this I get the error message "We ran into an installation error. This might be because your PC doesn't meet system requirement or your language isn't available". No further information is given.
My VMWare player is the latest version.
How can I get around this?
