What we distribute changes with our needs and with updates to Microsoft’s compiler tools. At this moment, we distribute:
VC2005 build 134278728
VC2010 build 167812379
VC2013 version 12.0.30501.0
VC2015 version v14.12.25810.00
If you need a newer C-Runtime, you’ll need to use a more complex MSI installer and chainer (we use Burn by WiX to do this) to install your prerequisites.
Or, you can change your plug-in compile to target the same runtimes that Rhino installs. Is there something in the new C-Runtimes that the V14.12.25810 build doesn’t have?
