Installation failed

After running this command: devtools::install_github("hrbrmstr/msgxtractr")
I become this failure msg:
Installation failed: Could not find build tools necessary to build msgxtractr

Rtools are installed and setted at path:
C:\RBuildTools\3.4\bin\make.exe
c:\Rtools\bin\make.exe

SessionInfo:

Running under: Windows >= 8 x64 (build 9200)

[9] git2r_0.19.0 digest_0.6.12 devtools_1.13.3

What can the problem be? I have tried it with remotes::github:install and githubinstall("msgxtractr") but none of them worked

Thank you for your help!

Do other C[++]-backed packages install from source? Installation failed: Could not find build tools necessary to build msgxtractr is definitely something being generated by "R"-proper and not as a result of the pkg (if it were the pkg the appveyor — https://ci.appveyor.com/project/hrbrmstr/msgxtractr — build wld fail). I shld have my local Windows VM environment back later this week (requires a VMware upgrade) and can see if there's a particular way the R tools need to be setup (I don't use Windows on a regular basis).

Ok, I understand the problem. I am going to try it with my linux machine tomorrow.
Thanks and have a nice day.

I had the same issue solved by a proper Rtools re-installation in the standard directory (C:\Rtools) instead of the default directory of the Rtools' installer. On the "destination" screen, change the installation directory to "C:\Rtools" and then check if the Paths are correct. For my part, on Win7 64bits, it solved this issue.
