Installation on Windows works fine. I have Windows 10 Pro. I installed in this sequence:
- R-4.3.2-win.exe
- rtools43-5863-5818.exe
- RStudio-2023.09.1-494.exe
I did a clean uninstall before I installed, even deleting the folders "R" abd "RStudio" in C:\Users[Username]\AppData\Local\
On the previous version, all worked fine since years.
