This is exactly the same thing that is happening with me on Poser 10. I have been using it for months without any issues. Windows 10 did an update and now Poser 10 will not load, I get the same error message that says Poser executable has stopped working. I tried deleteing the preferences, uninstalling and reinstalling. Nothing works since the windows 10 update on Dec 29th. It started crashing today Dec. 31st. The Windows 10 update is the only thing that has changed on my computer recently.
