2016 Turbo Tax Deluxe Windows 7 sp1 HP Pavillion m7 laptop To get installation to complete, I had to change permissions on folders ProgramData/Intuit. Don't know what they should be, but install completed with TrustedInstaller as owner and full control (find user trustedinstaller by typing nt service\trustedinstaller ). Installing as Admin and Admin has full control of those folders also. And thanks to the blogger who lead me to do this somewhere in my millions of searches. Turbo Tax tech support after 3 hours had no solution.
