That is, C:\Users\User\AppData\Roaming\gretl The "C:\Users\User" looks a bit odd. But if there is such a directory, does it contain a file named R.out? That's supposed to be where gretl gets R to write its output. Ah... and if doesn't contain such a file, does it contain a file with suffix .Rout, and content that looks like what you might be missing? If that's the case, then perhaps gretl is looking for the wrong file; I'm not sure why that would be, but it's fixable if so. Allin Cottrell

Or was it the path that gretl actually put into its error message? And does your AppData/Roaming/gretl directory contain any file(s) with suffix ".Rout"? Thanks, Allin Cottrell
