Unable to open Teststand 2016 in win 10

Hello All,

I am using win 10 PC and installed Test stand 2016 successfully. but when i tried to open the sequence editor i got error saying "Test Stand 2016 (16.0.0.185) must be the active version of test stand to use the sequence editor". i have installed Test stand 2014 also in my PC and tried. getting the same error.

Anyone knows how to resolve this issue?

Thanks,

Kalpana
