When I run an client that tries to create a COM object from R,
I get the error message
Error: R.DLL version does not match
Do you know what the problem is?
Yes, it is that system is finding a version of R.dll in your path
that does not correspond to the version of R_HOME that is used
to find the R packages. When we load the R.dll, that is found in your path.
When we find the R packages, we look either at the value of the R_HOME
environment variable, or we look in the registry to see if R_HOME has been
registered. The path and the location of R_HOME should agree.
