This is a strange bug that I encountered while running Gretl 1.9.5 portable of my usb drive using gretlnet.txt. I ran the program opened a file and in the Model->Time series menu i encountered that there some options missing. Those options missing were ARCH, GARCH, Vector Autoregression, Var lag selection, VECM, Cointegration test (anything bellow ARIMA). I suspect that the missing menus are because the portable version is conflicting with an older version of gretl installed on the computer (1.9.2). The older version was installed using admin right and so it cannot be removed. I suspect some registry entries might be at play. I can run the models using command line although I get a weird printout when i do GARCH (see attached images).
