Enabling the Launching of Creo View from Windchill Using SSL Client Certificates
Out-of-the-box, Creo View is not configured to use SSL Client Certificates, a requirement for it to correctly authenticate HTTP requests sent to a Windchill 11.0 server configured for the Public Key Infrastructure (PKI ) Authentication method.
As a result, when launching Creo View from Windchill, using the Open in Creo View action or by clicking on the Thumbnail, the following error message may appear.
Windchill request error
ATTENTION: Error occurred communicating with Windchill.
Contact your Windchill administrator for help.
This occurs if Windchill is configured to use Public Key Infrastructure (PKI ) Authentication.
To resolve this issue and enable the use of SSL Client Certificates when launching Creo View from Windchill, set the following environment variable to any value, for instance PVIEW_SEARCH_ALL_CERTIFICATES=<1>, in the runtime environment of Creo View on all client machines.
