We are running Windchill 10.0. I have one pc that can login okay, can find a part and when he selects the assembly he can select open in Creo View 2.0 and the viewer opens, but never displays the part. I have tried three different browsers, two different users on the computer and two different users on Windchill, so the problem appears to be the computer. I have checked Java version and that is okay, not sure what is going on.
this is not the area I have much experience with, but if the issue persists, a few ideas about what to check:
Hope this helps,
Using Creo (no matter the version) and saving a copy of the assembly as one of the four available files for Creo View, solve the problem.
