Help visual studio 2015

I got this error but in the right click retarget solution is missing

Anyone can halp ?

Open the project properties, and target another platform toolset.

Thanks but I installed v141 but it looking like not installed

Ok I found solution toolset v141 is for visual studio 2017 not 2015

I believe the 121 toolset is the last to be supported under 2015. For 141 you'll need visual studio 2017
