what blast version do you use? have you tried updating it? also, do you have write permission to the directory?

I think you are going to create db files under C:\Program Files\NCBI\blast-2.10.0+\bin\ .

The directory is for installed apps and basically you shouldn't touch anything around there (You don't have a permission to create the files).

Call makeblastdb from the directory where you usually use.
