When updating to Beta 4, Logos caused a Windows 7 crash, closing all open programs, and automatically rebooting the computer. I have always (since the early Beta days) had a problem with the updates, since I always received an error like this:

It has never been a real problem though, because after hitting "cancel" the update continues. I just have to manually start Logos afterward. This time, however, after I hit "cancel" my entire computer crashed, closing all programs, and shutting down, and rebooting. My setup file is attached:
