The process cannot access the file because it is being used

From time to time I get this error when attempting to start UE:

"The process cannot access the file because it is being used by another process. (32)"

On the second attempt it would start normally. I'm running Norton Internet Security, is the error related to the note on the download page?

yes, exactly, the antivirus checks the file while UE is trying to gain exclusive access to the file, i suspect it is not accidental, probably it monitors all files which are being opened and checks them in parallel thus introducing a race condition and causing sometimes the exclusive access file opening attempt to fail unless you exclude the affected directories from the scan.

from other side it is clearly not an UE error since exclusive access is a legitimate option.

maybe it is in the end microsoft fault if they don't provide any other documented option for antivirus software it is why they are now fined in EU for $370M :)

but nevertheless in the next version i'll remove the exclusiveness requirement so it shouldn't be a problem then.
