I have built a Slicer project with SlicerVR. I would like to use SlicerIGT in my project, so I directly install SlicerIGT and SlicerIGTLink in extensions-manager. Although I installed it successfully, it cannot open normally which is coming out those error,

I have already followed this link to download Visual C++ runtime to fix the problem, but it does not work.
