Installed the latest nightly build of Slicer and SlicerRT extension.

Lots of modules are missing (all that rely on Plastimatch) and the following is logged by Slicer:

Logged the loading process with sxstrace and got this:

ERROR: Cannot resolve reference Microsoft.VC90.OpenMP,processorArchitecture="amd64",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8".
ERROR: Activation Context generation failed.
End Activation Context Generation.

So, it seems that the installation package does not contain Microsoft.VC90.OpenMP. Installing VC2008 redistributable package would probably make the problem go away, but I'm not sure users could figure this out.

Either CMake (more precisely: InstallRequiredSystemLibraries.cmake) should be extended or the missing DLL should be added to the Slicer CMake files.
