I am creating a setup from python program (compiled with pyinstaller) successfully with Inno Setup. However, I call R functions with rpy2 in my program. Therefore I want the setup procedure check whether the user has installed R. If not, it can install R automatically. I found there are similar answers of .Net (https://engy.us/blog/2015/07/17/installing-net-framework-4-5-automatically-with-inno-setup/), but I do not know how to do with R.

  • Just run the R installer from the Inno Setup-made installer? The same way as any other dependency, like .NET here: https://stackoverflow.com/q/20752882/850848 – Martin Prikryl May 13 '21 at 08:25
  • Yes, but if it can be better for checking that only after successful installation of R, will the installation of my app continue. – H.Ji May 13 '21 at 08:28
  • See [Abort installation when dependency fails to install](https://stackoverflow.com/q/37131619/850848). – Martin Prikryl May 13 '21 at 08:29
