2.12 Installing Rattle on Windows Troubleshooting
Nothing Shows in the ROLES Page
On the first startup, after loading a Dataset, check the Console tab and wait until it shows the dataset summary. Rattle may be doing some R tasks to get things setup and this may take a minute or two. You can view the progress in the Console tab. Alternatively, before loading a dataset tap the R Package Installation button near the top right, next to Settings and wait for all the R packages to be loaded, then load a dataset.
MSVCP140.dll was not found
If the code execution cannot proceed because MSVCP140.dll was not found (and a few others) then install this Microsoft Visual C++ library from https://aka.ms/vs/16/release/vc_redist.x64.exe. Rattle should then start up next time you start it.
This will typically happen on a fresh install of Windows 11 where 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 in Section 2.9.
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,
for example, to check that R can find the rattle package:
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.
