Hi Tom and everybody, two questions: 1- I was trying to repeat the excercise about sewater evaporation as shown in the page 367-368 of the book Geochemical and Biogeochemical Reaction Modeling and when I try to run it (either from the graphic users interface or straight form the commands window) this error message appears "Error: "Could not operate REACT-Output XT file (Do you have write permission in this directory?)" This only happens when I use the Thermo-HMW database (which is the original the software came with). If I use Thermo.dat for example apparently has no problems. Can be just a mistake in the database? I used it for other modeling excercises and it worked. 2-Is there any place where I could see how to install the GWB 8.0.12 patch released? I downloaded the file but then I am not sure what to do. I would really appreciate any help with this, Best regadrs FER
