Why are you trying to install a second copy? If you have the idea that you can e-file more federal tax returns by putting in a second copy, you will not be able to do that. The five federal e-file limit is an IRS limit, and installing a second copy of TurboTax will not defeat that limit. If you have more than five they have to be filed by mail.
And if you already have a copy of desktop software installed and want a higher version then you can simply upgrade the version you have and pay the difference for the upgrade.
