I tried an installation of a program with Windows 10 Technical Preview but when I launch the setup it says: "This setup requires the .NET framework 2.0 etc."
Hi DiegoB1,
Try downloading the latest build of Windows 10 Technical Preview from http://bit.ly/15JPaEP and then try installing and check how it works. Refer to this article, http://kb.parallels.com/122745 for more information.
