3/15/2005 When you try to install additional weather files using the setup program, you'll get the error message "Cannot open file \Weather\groups.txt", then another error message "Cannot find weather file directory D:\Weather". To install additional weather files, copy them from one of the following locations: C:\temp\WEATHER C:\temp\WEATHER\Ca_Zones C:\temp\WEATHER\Interntl to the folder: C:\Program Files\Energy10v1_5\WEATHER (This assumes that you unpacked the archive to the default C:\temp folder, and that you installed Energy-10 to the default C:\Program Files\Energy10v1_5 folder.)
