With windows 10 update from 1809 to 1903, Creo 4 M40 doesn't start anymore (no error message), and Creo View 4.1 is unable to display 3Ds (Creo View starts and display the structure of the 3D models but doesn't display any 3D).
The computer used, a Laptop Dell Precision 3530 equipped with a Intel processor i5-8400H CPU at 2.5GH, Installed RAM 16.0GB & Integrated Intel UHD 630 Graphics processor, is connected to 2 Dell screens E2313H (1920x1080) through a Dell Universal Dock D6000 using a thunderbolt connection.
Creo 4 M40 and Creo View 4.1 with Windows 10 update 1903 can only start properly when disconnected from the dock station. Creo 4 M40 and Creo View 4.1 will continue to work properly when the computer is re-connected to the dock after being started undocked. Before the windows update 1903, Creo 4 M40 and Creo View 4.1 were starting and working properly with the Laptop and the 2 screens connected to the dock station.
Any idea of the source of the problem or clue for a solution without doing any regression in the drivers or windows update (IT security constrain - All drivers and Windows 10 shall be at the latest revision)?
In my opinion, getting latest datecode on one of the machines to test the issue can help. It may help in planning for next action.
Do you see xtop.exe in Task Manager > Details on starting Creo?
With several of the Windows updates we have seen computers need to have their graphics drivers updated. I usually try to stick with the latest one from the PC manufacturer (HP in our case, Dell in yours) but have had to to directly to Nvidia at times.
Some computers have the ability to set what graphics card is used for which display. You might look into that in the windows settings. The other thing I have done at times is to go into the BIOS and force the use of the Nvidia card. I'm not sure what the setting would be called in a Dell but in HP it has to do with the Hybrid graphics.
That sounds like a Dell/Windows issue then because I presume that it was working before through that interface and Creo definitely would want the Nvidia graphics. It looks like the BIOS setting on the Dell would be tied to the Optimus setting.
Have you tried using the hidden config.pro option for graphics?
It might allow Creo to start at least.
I don't have much details about thunderbolt dock but as far as I know there are inbuilt graphics card in it. If you get a chance try disabling the inbulit graphics in dock.
Do you license manager on same machine for it is on some other server?
