In the past we have always ordered the versions that came on CD, installed them on the same computer and used Premier for our personal taxes and another purchased copy of Business/Trust for the family trust and have never had a problem in the past with having both instances running at the same time so we can run the numbers on both returns open at the same time.

Fast forward to this year and now CD version are no longer available, so we purchased the downloadable versions.  Installed and updated both but now we are unable to run both versions at the same time as in years previous and get the dreaded  "Error 70001 "TurboTax is already running under another account."

Any technical solutions to solve this problem?
