Parallels 10 Win7 and WinVista iso installation

I am able to load the iso (both for Win7 and WinVista, non-OEM) and get past the serial number entry. After that, it goes into a command window and says it cannot load from DVD/CD 0 (SATA 1) where I have the iso loaded. I have no CD drive on this computer so using the disc itself is not an option. I followed all of the advice in this previous thread from Parallels 9 (https://forum.parallels.com/threads/parallels-is-not-seeing-my-cd-dvd-drive.261615/page-2) and nothing worked. I am in the exact same spot as the person who posted it. Neither iso is corrupted and the setup.exe files are in there. Why would it start to install, make me enter the serial number, then fail?

 

Hi Haleys,
Please try to download the Windows 7 iso image file from here. and then try to install. Please check how it goes.

 

That worked! Thank you!
