Hi all,

do I still need the Visual C++ Redistributable on the target system when linking to the dynamic runtime with a recent VS2017? Based on Fabian’s post about dynamic runtime linking I got the impression that Windows 7 and onwards now includes all necessary DLLs when they are on the latest updates… Is that true?

If you do not override the default setting in the Projucer, then this means that you must ensure that the Windows runtime is installed on your customer’s computer for your plug-in/app to work.

IIRC, the toolset that comes with VS2017 is number `141`. `140` would be the toolset of VS2015. Maybe your binary depends on something that was built with VS2015.
