Environment:
QlikView any version
Resolution:
In such a case, you can first try to move this application away from the QlikView User Document folder so that the QlikView Server service won't try to load it.
If it works you can then investigate the corrupted application using How to handle corrupt objects in QVW or corrupt QVW.
