PTV Visum - Frequently Asked Questions (FAQs)

(#VIS25390)

Every time PTV Visum/PTV Vissim is started, a dialog is shown:
'A license update was installed on the CodeMeter stick. Therefore you need to select new licenses.'
'You have installed a license update on the CodeMeter stick. Therefore you need to select new licenses.'

When in the dialog 'License Management' a license has been selected and confirmed with the button 'Start' an error message is shown:
'The license data could not be saved to file 'c:\ProgramData\PTV Vision\PTV Visum 18\licenses.data':
Access to the path 'c:\ProgramData\PTV Vision\PTV Visum 18\licenses.data' is denied.'

The file licenses.data was once defined by an administrator.
1) Workaround if it is not needed anymore:
- Open a Windows Explorer with administrator credentials.
- Delete the file
licenses.data
from the folder
%programdata%\PTV Vision\PTV Visum xx\
(if present)
- Restart PTV Visum once as Administrator and select the license in the dialog 'License Management'. If the dialog is not shown: Help -> License -> Manage licenses.
This will overwrite the file:
%AppData%\Roaming\PTV Vision\PTV Visum xx\licenses.data

2) Workaround if it is still needed:
- Start PTV Visum/PTV Vissim on one client.
- Select the correct license.
- Copy the file
licenses.data
from the folder
%programdata%\PTV Vision\PTV Visum xx\
to all other clients.
