(#VIS27336)

The following error message appears when starting PTV Vissim:
- '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.'

The setting from the license selection is saved in the file 'licenses.data'. If this file contains an invalid setting, the error message will be displayed.
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.

- If available, delete the file 'licenses.data'.
- Open the path %programdata%\PTV Vision\.
- Open the Vissim folder (e.g. ..\PTV Vissim 2020\ ).
