PTV Visum - Frequently Asked Questions (FAQs)

(#VIS29882)

Opening a project in the Scenario management fails with an error message:
'Connection to database failed. If the SQL server CE 3.5 is not installed properly, you can proceed as follows:'

The Microsoft hotfix, that solved this issue in the past is not available anymore.

Workarounds:
- Make sure Windows 10 is up-to-date and all updates are installed.
- Replace SQL Server CE by SQL Server Express, which means the database is no longer a file on a network drive but served by a database server on the network instead.
- Change to PTV Visum 2020, which used SQLite instead.
- Store the project on a local drive.
