Good morning ,
There is an error on installing V 1.0b5.4
Hi @jamesplank if you have an old version installed, just starts it and choose "Check for Updates..." under the Creo menu. When the "New version" notification window will appear just click on the Here link.
If you don't have an old version just send me an email to marco at creolabs dot com and I'll send you a direct download link.
