There is no doubt that if you run multiple instances, there must be at least a theoretical possibility that two or more instances will require access to a file at the same time, and I am certain that I have such contention troubles in the past. As I have suggested, assuming that only one instance is downloading any one particular programme, the most likely culprits are the shared download history and caches. However, there are various things that might alter how much of a problem this might be in practice, for example here are two: 1) The OS - the OP was working with Windows, while all none of his respondents are. It might be that Windows is less forgiving of attempts by one process to access a file that is currently being updated by another process. 2) The speed of the hardware. It is likely that filesystem timeouts are fairly accurately timed and constant across different hardware, while the time taken to actually update a file will be determined, or rather inversely determined, by the speed of the hardware. Therefore, the faster the hardware, the less the likelihood of a contention causing a timeout. I have fairly old hardware.
