PTV Visum - Frequently Asked Questions (FAQs)

(#VIS27336)

The following error message appears when starting PTV Visum:
- 'The requested license (server: .., license number: ..) cannot be used ..'
- 'The selected license (server: .. box: .., license number: ..) cannot be used, since the related CodeMeter stick is not available.'
- 'The selected license cannot be used, since the related CodeMeter stick is not available.'

- Check whether the current license matches the started yearly release version. Typically the current License activation ticket was not yet activated.
- Check that the correct dongle is plugged in.

The setting from the license selection is saved in the file 'licenses.data'. If this file contains an invalid setting, this error message will be displayed too.
The solution is to delete this file. This forces a new license selection.
Depending on the configuration, this file is in %appdata% or %programdata%.
Important: Changes in %programdata% are only possible with administrator rights.

- Open Windows Explorer.
- Open the path %appdata%\PTV Vision\.
- Open the Visum folder (e.g. ..\PTV Visum 2020\ )
- If available, delete the file 'licenses.data'.
- Open the path %programdata%\PTV Vision\.
- Open the Visum folder (e.g. ..\PTV Visum 2020\ ).
- If available, delete the file 'licenses.data' with administrator rights.
