Visu error messages after uninstalling older PLC Designer versions (fixed from V3.22)

Corrected from:
PLC Designer V3.22

Response of the new version:
Uninstalling PLC Designer V3.22 does not damage the library repository.

What happens?
  • When compiling a project the following error messages appear:
    Could not open library '#System_Visu[xxx]'. (Reason: The placeholder library [xxx] could not be resolved.)
  • Visualisation elements are missing on visualisation pages in the PLC Designer project.
  • The tab 'Visualization Toolbox' does not contain any visualisation elements.
A visualisation page can no longer be created or edited.

When does the behaviour occur?
The behaviour occurs after a PLC Designer V3.19, V3.20 or V3.21 was uninstalled and no newer PLC Designer >= V3.22 was installed afterwards.
 
Which products are affected?
PLC Designer

Short-term measures:
Reinstall PLC Designer V3.22 (or higher).

Remark:
It is sufficient to reinstall PLC Designer V3.22 (or higher). Uninstalling and then reinstalling is not necessary.
 
Evaluation/Recommendations:
During uninstallation, the library repository is damaged, which is accessed by all installed PLC Designer versions. The PLC Designer project itself is not affected.
