I've got an VB.NET application that was written in-house by a former employee. The application generates a report using a Crystal Reports dll. Unfortunately, there is no documentation, the app cannot be fixed and recompiled, we are simply stuck with the install program associated with the app.
When trying to generate a report, we get the following error:
interop.crystal exception from hresult
I've reinstalled the app hoping it would bring in whatever it needs to run, but no luck.
Any suggestions on what to do to get it to work?
