TBS says I need to Install Quick Time even though I did

I downloaded the 15 day trial of Toon Boom Studio and downloaded Quick Time exclusively for it but when I try to run the application an error message pops up stating that I need to download QT. Does anyone have a solution or suggestions on how to fix this problem.

run the program as administrator and it should be fine.

try install QT latest version.
maybe will fix this problem.

Did you restart your computer?
