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.
