Corrected from:
PLC Designer V3.20
Response of the new version: No exception occurs anymore if the <Back> button is clicked in the 'Install Licenses' dialog.
What happens?
When using the license manager, an "Unhandled Exception" occurs.
When does this behaviour occur?
When installing a license via the License Manager (menu command 'Tools > License Manager > Install Licenses'), an exception occurs if the <Back> button is clicked in the 'Install Licenses' dialog.
Which products are affected?

Short-term measures:
Short-term measures: Save your project before installing a license in the License Manager. Do not use the <Back> button in the 'Install Licenses' dialog.
Evaluation/recommendations: The installation of licenses with the License Manager is possible. However, if the exception described above occurs by using the <Back> button, the PLC Designer terminates and data that has not yet been saved is lost.
