Hello Juan,
do I understand correctly that Creo tries to connect to a Windchill server (workspace), when you launch it, but never gets to an end?
Most people attending the community do not speak Spanish, so it is best to ask in English.
I used Google translate, but the part with the "planes" is not clear to me - maybe a misinterpretation of Google?
Translation (source Google Translate):
I have had a problem to install the I 2.0, whenever you complete the installation and open it to begin work appears a page of servicion to think but to try to open the workspace with planes it does not appear and this page does not closes, someone could help me know why this is and how can I fix?
