I had to enter a new administrator user acct on my Imac 10.10.5 and am having great difficulty in installing my Windows 10 (automatic download from Microsoft) into my new user account. Parallels 10 is reinstalled, but apparently there are components missing to reinstall Windows 10. The Windows.pvm is in my documents folder but I'm stuck. The components I must need are in the other user acct. Can anyone help me make this transition? I don't have the DVD; I upgraded from Windows 7. I am not an expert but usually can follow through if instructed. Thanks in advance for any help.
