I have loaded all the software and was able to generate a schematic but I am unable to launch the Layout app. I get a windows system32 error and PCB Editor fails to responds. For example, after I sign on, open Capture, and try to launch PCB, I get the screen image below.  



Then I click the OK button, and then get this error (NOT Responding).




To resolve this issue, open a DOS command shell and issue the following command:

C:\Cadence\SPB_17.4\tools\bin\allegro -safe

If that doesn't work any better try this command:

C:\Cadence\SPB_17.4\tools\bin\allegro -noopengl


If neither of these are successful restart PCB Editor by right mouse clicking the shortcut (icon) for PCB Editor then from the menu select "Run as administrator."
