When I install IDL and ENVI on my Macintosh with Yosemite, the License Wizard does not appear as the instructions state, although the install produces a message that the installation was successful. When I try to run IDL/ENVI, I get an error message that the license file is not found. It is the case that the license file is not in the directory 'license' where it is supposed to be. If I knew the format, I could make my own and see if that worked. If I try to run the License Wizard, it runs for a very short time and quits. The only way that I know it runs is by watching the Activity Monitor. There is no indication that it runs otherwise.
