Opening a version file

Note: Visum version files are not downwards compatible. This means you cannot use an older Visum version to open version files created in a more recent Visum version. For example, you cannot open a version file of Visum 22.01 version file with Visum 22.00. The bug fix version number, appended to the actual version number with a hyphen, is ignored in this context (Help menu > License > Version).

1.  From the File menu, choose > Open.

In case of unsaved changes to the current network, a security prompt appears.

2.  Confirm this security prompt.

The Open: Version window opens.

3.  Open the desired file.

4.  Click the Open button.

Note: Depending on the contents of the version file and your settings different queries or warning will be displayed, which you have to confirm.

The version file is opened and the name of the version file appears in the window header.

Notes: Which windows are open after reading a version file depends on your settings (Making settings for windows upon opening version files or program start).

If you open a version file larger than your license permits, a warning is displayed that says Visum is in the oversize mode. The title bar indicates the oversize mode when the network is too large. You cannot save the version file in this mode. Reduce the network to license size (Subnetwork generation) to use all functions and save the network file.

Besides the Subnetwork generator, you can use the following functions in the oversize mode:

  • Edit network
  • Make screenshots of network and timetable
  • Execute COM scripts

Tips: Alternatively, you can open a version file by clicking the selected file in the list of recently opened files on the File menu or by drag & drop. Drag the version file from the Windows Explorer into the program window on screen.

Alternatively, you can have a version file opened automatically during program start (Changes to settings in the configuration file).

Alternatively, you can open a version file by double-clicking the version file in the Windows Explorer. In this case, a specific project directory file (aktdrv.pfd) is used for the start. It ensures that Visum browses for referenced files in the directory where the version file itself has been stored.
