Applies to:
DecisionTools Suite, textbook edition

Error:
"There is no available license"

Cause:
The textbook software does not require activation. 

If you run the installer from within the .ZIP file (compressed folder), it will not find your textbook license and will install itself as a trial.

Solution:

During installation, extract all files from the .ZIP file to your desktop (or preferred location), and then run the installer. 

After installing, you can delete the files that you extracted to your desktop.
