However, even though I specify at the end of the installation to launch VirtualBox, the program never appears to start. Starting the application manually has the same result. I checked out the Task Manager, and it appears that VirtualBox.exe does start, but dies within a few seconds. Again, checking the Event Viewer, I can see the following error: (see attached) Under VirtualBox 4.1.2, there is also the following message in the log found under my windows profile in the .VirtualBox folder: (see attached) Rebooting hasn't appeared to solve the problem. I do have drivers for a Wacom Bamboo tablet installed, though I haven't had the tablet connected at all throughout this process. I posted this to the forums previously, and was directed here. The link to that post: https://forums.virtualbox.org/viewtopic.php?f=6&t=44866 Thanks so much for your help! Jason" defect closed host support VirtualBox 4.1.2 worksforme other other
