Ну могу установить Windows 7.. при запуске программы установки выдает такое: SPWIZENG.DLL is either not designed to run on windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc0000020. и еще одна : the file "autorun.dll" could not be loaded or is corrupt. Setup cannot continue. Error code is [0xC1]
