I need to install keys for Marvin to be able to run calculations within IJC such as cLopP.
I went to Tools/Options and there are several places to enter several other keys, but none for Marvin.
Thanks much in advance for your help.
I'm not clear on this: Do I need to install Marvin separately?
So far I have only installed IJC on my Windows XP machine.
I searched for the licenses.dat file in the hard drive, but no file with that name was found. (?)
OK, I had wrongly assumed that you had Marvin installed. Without that the licenses file will not exist and you will need to create it yourself.
Create a text file named licenses.dat and place it in the
.chemaxon (Unix - note the dot at the start) or chemaxon (Windows) directory within your home directory. e.g. on Windows this will be something like
C:\Documents and Settings\username\chemaxon\licenses.dat
where username is your actual username.
Alternatively you could install Marvin and enter the license keys using that. Marvin Sketch and Marvin view are userful to have even if you are mainly using IJC.
