I copied the ucrtbase.dll into my I:\Hybrid\64bit\Avisynth folder, started Hybrid, switched "Filtering->Support" to "Avisynth", changed "Config->Internals->Avisynth->Avisynth type" to "64bit", loaded a source started the Avisynth Preview.
avsViewer64 was started without a problem, but it's still using the dll in the system32 folder.
What I found was, that the avsViewer64 build in Hybrid was build against another C++ runtime version.
-> build a current version and attached it with the dependencies.
Try whether that version works for you. (extract all the files in your "Hybrid\64bit\Avisynth"-folder)

Ps.: btw. your avsViewer64bit command line call uses double backslash which it should not. If you are uncertain if you need to escape backslashes, try using slashes instead. (not sure about Win7 but Win10 does support using slashes instead of backslashes)
