We are running long term tests with multiple GC analysis, automatically controlled from LabVIEW via ActiveX communication with OpenLab EZChrom.
We recently had an event in the EZChrom software creating problems;
suddenly midway through the tests, the analysis started to fail. The communication seemed to fail,
resulting in an error that suggested OpenLab couldn’t locate its core license. The problem was solved by entering off-line EZChrom software to copy license, erase license and ultimately re-paste license. Communication returned, and the test could continue.
Anybody seen these strange things that the license system seems to break down during testing ?
Rather hopeless bug to fight with......
