I am trying to install Windows 8.1 x64 OEM on a iMac late 2013 with an i7 processor using a Windows supplied DVD including what should be a valid key. When installing the Windows as part of the install process requires you to input the key which it checks and reports it as invalid. The version of Windows I have been sold is for system builders [OEM] is this version compatible with Parallels 9?
Hi AnthDN, Please follow the below article and uncheck the option to enter a product key on Step 4 while installing Windows: http://kb.parallels.com/4729 Thanks, Looran
