Error: License file has expired

Version: 3.5x - Scientific WorkPlace, Scientific Word, Scientific Notebook

Problem

SWP or SNB was purchased and installed following a 30-day trial. Opening the program results in a message similar to this:

Your trial or fixed duration license file has expired. Contact MacKichan Software to purchase a permanent license.

Otherwise, the program works correctly.

Explanation

The trial version contained two computational engines (MuPAD and Maple) but only one was purchased. The licenses directory in the program installation probably contains two licenses, one for the 30-day trial and one for the purchased installation.

Solution

Modify the license file to remove the licensing information for the 30-day trial:

1. Using an ASCII editor, open the file license.lic in the licenses directory of your program installation.
2. Delete the unnecessary material in the license file:
   • If you have SWP, delete all the lines in the file except these (Xs represent numbers particular to your installation; either Maple or MuPAD may be specified, depending on which engine was purchased):

     ***********

     FEATURE SWP_Maple All mackichn 3.5 permanent uncounted XXXXXXXXXXXX \

     HOSTID=COMPUTER_ID=XXXXXXXX

     # XXX-XXXXX-XXXXX-XXXXX #

     ***********

   • If you have SNB, delete all the lines in the file except these (Xs represent numbers particular to your installation):

     ***********

     FEATURE SNB_Maple All mackichn 3.5 permanent uncounted XXXXXXXXXXXX \

     HOSTID=COMPUTER_ID=XXXXXXXX

     # XXX-XXXXX-XXXXX-XXXXX #

     ***********

3. Save and close the license file.
4. Make sure the file is still named license.lic after you save it.

   Some ASCII editors add different file extensions, such as .txt, to the file name. If the editor has added an extension to the file name, change the name to license.lic.
