In November 2013 I've bought Sql Server 2012 Developer Edition and installed it in a Windows 8.1 (in Try mode) Vmware virtual machine and worked great.
Recently, I've bought a new lap top with Windows 8.1 but the same Sql Server does not install, neither giving the product key nor requesting Try mode.
In both cases the error is Data Error (cyclic redundancy check)
Is it possibile that the DVD is unreadable ? It's been usedjust once and stored normally in his own package !
In this unfortunate case is it possible to recover the software from Microsoft Online or somewhere ?
Thanks for any help.
