The PyXLL add-in requires a valid license after a built-in evaluation period. After your evaluation period has ended, if you do not have a license, or if you've not configured your license correctly, you will see the following error. The only reason you will see this error is because there was no license key found.
If you have a license but you still see this error, the problem will be that the license key has not been configured correctly.
Check your pyxll.cfg file and add the license key exactly as it is in the email you received containing your license key:
[LICENSE]
key = your license key goes hereIMPORTANT: In the example pyxll.cfg file, the license key line is commented out with a semi-colon ";" character at the start of the line. Make sure in your file the license key is not commented out.
If you have configured the PyXLL add-in to read the license key from a file as follows, check the file name is correct and that the file is readable. If the file cannot be read you will see a warning in the log file in addition to the error shown above.
[LICENSE]
file = path to the plain text license file must be readableIf you are still having problems after carefully checking your pyxll.cfg file, check the log file - Where is the PyXLL log file located?
Configure debug logging to get more information about what's going on by setting "verbosity = debug" in the "[LOG]" section of your pyxll.cfg file
[LOG]
verbosity = debugWith this set, you will clearly see if the license key has been configured or not in the log file.
If you do not have a PyXLL license and no longer wish to use the add-in after your evaluation period, you should now uninstall the add-in to get rid of this error - How to uninstall PyXLL.
