I´ve a academic licens for JChem for excel. But when I installed the MarvinBeans on the computer JChem for Excel stopped working. When I press on the symbols for example: Smile to structure. Then, nothing happends and the symbol becomes grey and I cant press it again. Do you know the reason for that? Should I maybe re-install the program and then put in the academic license file again? This happened immediately after installing MarvinBeans before the installation it worked perfectly.
