Wonder if anyone has experienced similar issue and what was the workaround for the problem - I had PI Builder Add-in working fine for a while after initial clients installation on my desktop, however it has stopped working now and nothing seems to help (repair, uninstall/install of software).
When I go to the excel>Add-ins, PIAFBuilder is showing in the COM Add-Ins available list, however it is deselected and when I select it again nothing happens.
When I try to add it by going to the AF folder and select an PIAFBuilder.vsto it says it is "not a valid Office Add-in".
The version of the PI System Explorer is 2018 SP1.
Thanks in advance
