2.9 Installing Rattle on Windows Troubleshooting
MSVCP140.dll was not found
On a frsh install of Windows 11 you may need to install the Microsoft Visual C++ libraries for running the flutter app. See answers.microsoft.com. From there you can download and install one of vc_redist.x64.exe or vc_redist.x86.exe.
Process Exited With Exit Code
This will occur if R can not be found in the PATH. Be sure your PATH environment variable is properly set as described earlier.
Checking R Packages Available
With the install of the R packages, Rattle should find the appropriate packages. Test in the Console tab by typing the following command:
If the package is not found then be sure to check that you installed the packages with R.
R Packages Not Found
The R process within the Rattle app might not be finding the locally
installed R packages. When that is the case Rattle will attempt to
install them for you. But if the paths to the location of the
instaleld pacakges is wrong then Rattle will not find the
pacakges. You may be able to see this if you compare the output of
.libPaths() in the Rattle Console tab to the output when you run
R in your Command Prompt. The Rattle version may not have your local
path (e.g. C:/Users/fred/AppData/Local/R/win-library/4.4) and it may
only have the system path (e.g., C:/Program Files/R/R-4.4.1/library). A workaround is to ensure your packages are
installed by the Admin user.
