Hi,

Since last Win10 update we've been experiencing Access violation exception within version 5.53 of your libraries.
We've tried updating the packages to the latest version 5.58 but starting from 5.55, our multipurpose license is not recognised at all.
This license is still recognised under license manager.

Exception:

"Not allowed to run by the license "Multipurpose". You might be using a trial license, and the version of the software you are using is obsolete. Obtain a recent version to resolve this problem.
Component name: "QuickOPC", license IDs: "Multipurpose", version number: 555, release date: 17/09/2019, trial validity: 210 days, option name: "EasyUAClient"


Could you advise?


Thank you
