Lighthouse LMS Express 7 crashed
This is the commercial software controlling the Lighthouse particle counters in the H1 PSL enclosure. Logging into h0dust (Windows 7 Pro SP1 64 bit virtual machine) through VNC this afternoon I found the error message in the attached pictures. I found two related events under Event Viewer (Local) -> Windows Logs -> Application on 2/7/2014 11:02:01 AM. The text of the errors is attached. Searching for related information I found the following: http://support.microsoft.com/kb/2640103

It looks like the LMS software install includes the .NET 4 runtime, but it was probably out of date at install. 4.5.1 is available through Windows Update, I would assume it includes the fix mentioned in the KB article (since it's over a year old now), but I haven't been able to confirm what's included in the update. It's probably the first thing to try though, but it means downtime for the updates to install.
