#77 DPWS Explorer Crashes on Startup with NullpointerException at IPDiscoveryBinding

[Gero Kraus]

Hi,
on 32Bit Windows machines (at least the two I tested), the DPWS Explorer 3.13.6 keeps crashing on startup. Earlier versions worked on these machines.
The Stacktrace is a follows:

[INFO ] The DPWS Client of the DPWSExplorer is starting... Please wait!

Hi Gero,
please try to delete the persistence folder. This should fix the problem.

Best regards,
