I've used the option to upgrade SQL Server 2008 to R2 but I noticed it gets to about 20-30% and it just sits on this screen: I've left it alone for over 2 hours, the PC is definately not frozen cause I can click the help or move the window around but it says "Install_sql_common_core_loc_Cpu64_1033_action: Install Files. Copying new files" for the past 2 hours. I have tried to do the install from a CD as well as a network drive, both with the same issue. Is there anything I can check or do ?
