Proper installation of microsoft R open 4.0.2 under windows 8.1... or not?

I just installed microsoft R open 4.0.2 (installation side-by-side with R 3.6.3) on my computer running under Windows 8.1. The installation seems correct at first glance but I have a serious doubt because when I look at the session information, the matrix product is set to "default" without any indication of BLAS and/or LAPACK. Also when I run the extSoftVersion() command, the "BLAS" field is empty... (cf. below)

So, I would like to know if:
1-my installation is, or not, correct
2-If not, what I can do to solve the problem.

Thanks in advance,
