RStudio IDE not displaying render or recognizing .qmd files

I am using RStudio version Version 1.1.456

and I have R version

I am not seeing the "render" button and RStudio does not recognize .qmd files. If I use the 'create project' option from RStudio IDE there is no option to create a quarto project.

Any ideas?

Your RStudio version is too old, it doesn't have Quarto support, you need to update it if you want to have the Quarto integration features.

However, Quarto is a stand-alone software so you can also use it through its command line interface if updating RStudio is not an option.

Thank you.

I have installed the latest RStudio but sometimes my computer defaults to this pervious version, so, apparently I have multiple versions of RStudio installed.

This is another version I found on my machine:

RStudio 2023.03.0-daily+70 "Cherry Blossom" 
Daily (236fd07b9b86d184ae614fffe20e44f8f2b1937b, 2023-01-09) for Windows
Mozilla/5.0 (Windows NT 10.0; Win64; x64) 
AppleWebKit/537.36 (KHTML, like Gecko) 
RStudio/2023.03.0-daily+70 Chrome/108.0.5359.62 Electron/22.0.0 Safari/537.36

Is there a way to remove the old version?

Is there a good up-to-date reference to update update R and RStudio?

That is weird, normally new versions overwrite the old one unless you intentionally choose a different install location. You can remove older versions on Windows from the "Programs and Features" config tab.
