How to delete certificates of UA.Testclient

[Marc_S]

Is it possible to delete the certificate of the UA.Testclient on my pc (remove PKI)? If yes, where are the certificates located?

I want to create a new certificate with an actual date on my engineering station. But i don't get the "Create Certificate" window shown again.

You can reset your PKI by deleting all certificates and private keys (normally one each):

C:\ProgramData\Rexroth\PKI\own\certs\UA.TestClient*
C:\ProgramData\Rexroth\PKI\own\private\UA.TestClient*
