When I try to run Allegro CL 7.0 Trial, it fails with the error “missing or invalid license file”. Why?

A 4.6-2) The license file you received from the URL sent to you by email after you requested a Trial version must be saved to the file devel.lic in the Allegro directory. Because Windows tools for saving files are often mysterious (since they automatically do what Windows thinks you want to do), the file is often saved an devel.lic.txt or devel.lic.htm, rather than devel.lic. You can see there is a problem if you look at the file in the Windows Explorer and the type is shown to be anything other than LIC file. If the file has a type that is anything other than LIC, select the file in the Windows Explorer, right click and choose Rename from the menu that appears. Then type `devel.lic’. You may get a warning saying that changing a type often is destabilizing and asking if you really want to do it. Answer yes, you really do. (UNIX users rarely have this problem because file saving is more transparent on UNIX.) Now you have a file whose name and type are devel.lic in the Allegro directory.
