After starting the WebModel export, viflow 6 will immediately stop. You can see the small loading bar at the bottom left, but it does not move anymore and the large loading bar in the center of the screen is not displayed. The problem only occurs with Microsoft Visio 365.
The export is not finished even after a long wait.
To solve the problem, an online repair must be performed for Microsoft Visio / Office 365.
To do this, go to the Windows Control Panel under Programs. Start the repair process by right-clicking Microsoft Visio.
You will be asked how the repair should be carried out. Select the online repair and start the process.
Then the WebModel can be exported again from viflow 6.
