Hi again,

Thanks for the swift reply.

Is it the fact that the machines has been upgraded from an older Windows to e.g. Windows 10, that you often see this issue occur?
Or is this just an issue that happens in some rare instances?

Best regards

Hi,

We have a OPC service, which is using your EasyOPC library for .NET Framework 4.5.2 (OPCLabs 5.53.405.1).

The software is being installed on multiple machines, however some times, it doesn't create the certificate.

I've tried many different approaches find the issues, different ways to try and connect but nothing helped. Neither getting the certificate created or getting a different error message.
The only ways I've made it work have been to start as administrator, close if fails and try again. Then sometimes it succeeds after quite a few tries.

The machines we are installing it on, are sometimes a machine with an older Windows installed, which has been upgraded to Win 10.

Have you experienced anything like this, that might point me towards what the issue could be, cause I've been struggling with locating the issue for a period of time without luck?

Every attempt has been as administrator.

Best regards
NAX
