Lookout executable has stopped working

Windows gives me the error 'Lookout executable has stopped working'.

 Lookout 6.6 development version, Windows 7 on Dell Latitude.

This occurred a couple of times now, and the only fix is to completely reload Lookout.

Has anyone seen this problem before?

Some drivers can cause this.


We have an Ethernet serial convertor and if the network drops, lookout will hang.  If you click the screen, it will stop responding.  After the adapter is reconnected, lookout usually recovers within 2-5 minutes.


Have also had happen with a lot of Modbus TCP sites and changing datamember aliases.

That happens here when opening panels with multiple trends, I would like to be able to fix that too, but this is another issue.


This problem causes the Lookout executable to be corrupted in some manner that it will not recover, I have not been able to get it back, short of reloading it completely. The only common factor I have seen so far is, it occurs when I have been editing something with Object explorer. Very frustrating….

In object explorer, doing multiple right clicks (menu), editing data members, connections, etc.  The cursor becomes a "Not Available", Red crossed symbol.  Any further clicking crashes the program.


By reloading do you mean uninstall-reinstall?  Or just click icon again?

Reloading from disk, reregistering with NI, complete new install.

Wow, cant say I have experienced that severe of an issue.


ryan.shi(@)ni.com is a more direct Lookout support link.  Though if you dont have an active "service plan" they may not help too much.

Since 2014, did you found a way to fix the problem when Lookout become not responding?


I know we can do a complete reinstall but if somebody found another way...

Sure did: replace it.

NI doesnt provide even a hint of support for Lookout anymore.

Lots of options out there now.

We went to ClearSCADA (GeoSCADA).

Inductive automation ignition, wonderware, vtscada, daqfactory; find one that fits your industry.
