white working window no parts/layers are visible...

Hi,

I guess the problem is related to graphic card drivers. What graphic card is installed in your computer?

1.) add graphics  win32_gdi at the end of config.pro file and start Creo ... what can you see?

2.) if step 1. was successful then update graphic card drivers (... and remove the above option from config.pro)

You can also try changing the color scheme to use a dark background. This will reveal if your model geometry color is the same as the white background.
