During evaluation of QuickOPC I always get this error. Something seems to be wrong with my certificate store or maybe it is because the computer is Azure-AD-joined.
I already tried deleting all stored certificates with the "UA Configuration Tool".
The simplest step to reproduce the error is to call "EasyUAClient.Install();", but it also happens for the "Read"-Methods of the EasyUAClient.
The only workaround I found is to run the application as administrator.
Using the Official OPC UA .Net Standard Stack (1.4.356) in the current version directly, the error doesn't occur. I saw that the toolkit does't use the current version. Maybe an update of the embedded SDK could help?
Tested Versions:
5.54.1311 net46
5.55.0-rev12 net47
