Hello Friends I´m installing Win 7 on various machines in the last period. I use SLIC activation on all of them but i noticed one problem. When i try to activate manually and try to install the Cert with the command "slmgr -ilc C:\NAME.xrm-ms" Windows return with a Message that the version i am using is not a Core version of Windows and the error is "slui.exe 0x2a )xBBA" . When i use Windows Loader and install only the Cert and the Key everything works great. Can someone explain me please why this error happens when i try to activate manually? The win 7 iso i used is pt_windows_7_ultimate_with_sp1_x64_dvd_618549 for 64 bit and pt_windows_7_ultimate_with_sp1_x86_dvd_618754 for 32 bit. Can anyone tell me where i can download the MSDN or Original SP1 of PT/BR version please if the version i have is not the right. Thank you!
