Getting PI SMT Unhanded Exception error, Please let us know workaround.
Does it happen every time? I have had PI-SMT crash on me many times but starting the program again usually works.
You may need to try a repair of PI-SMT from Add/Remove Programs in the Windows control panel.
Which version of PI SMT is this?
An application can crash for any number of reasons. Knowing the exact steps that are taken to cause the crash are typically crucial in determining exactly why any application may be crashing.
That being said, the crashing stack matches the following work items:
PI SMT Current Values Plugin may not display the tag search dialog, or may crash in certain scenarios for single server
PI SMT Current Values Plugin may crash when adding duplicate tags to live list of existing tags
The first known issue is resolved in SMT 22.214.171.124 (you appear to have 126.96.36.199), so the latter work item is likely more applicable. If those reproduction steps apply for you, I would recommended only adding tags from a single collective member to the current values plugin at a time.
If this is not applicable, I would recommend opening a Technical Support case so that a crash dump can be gathered for further analysis.
