Just before a time critical job we started to get an error when loading worksheets in Dasylab 10.0.3. It was one of those 'windows has encountered an error and needs to close' things. Looking at the details it said the problem was with displ1.dll.
It made our saved worksheets unuseable as they could no longer be loaded into Dasylab without the crash occuring.
I eventually got around the problem by deleting displ1.dll from the \windows\program files\dasylab 10 folder then running Dasylab.
This allowed me to open our exisitng worksheets but with a red cross on modules that required displ1.dll - notably the yt chart and the list. If I deleted these modules, I could at least save and re-use the worksheets (but without our chart and list displays).
My quick workaround solution was to then re-instate displ1.dll and reload Dasylab. I could now open my old worksheets - because they had none of the modules that needed displ1.dll in them. Before starting my data acquisition, I could then manually add the yt chart and the list displays and then commence with the work. No problems as long as I didn't save the worksheet with a yt chart or list on it - if I did then then I would get the same error as previously described. So, with timescales short (a matter of hours) I came up with a 75% work around solution that required minimum re-work whenever we wanted to use the worksheet.
Has anyone encountered this problem before and why is it happeneing?
In my initial confusion, I uninstalled Dasylab then re-installed as 10.0.1 to see what would happen. Still got displ1.dll error. Then I applied service pack 2 to take the install back to 10.0.3 and it still didn't work. I note that there was a new version of displ1.dll in SP2.
We have been using Dasylab 10 for a number of years with the same DAQ hardware (IOtech Wavebooks) for a few years now with no problems - how come this problem has seemingly emerged from nowhere?
