The first time I ran the tool the iso was for both 64bit editions which wouldn't fit on a 4gb flash drive for the obvious reasons but was mistaken for the 32/64bit combo for 10 Pro until examination later once on the drive due to replacing a drive actually revealed that one. That was solved fast however by sdownloading the 64bit and later finally the 32bit Pro ISOs separately over the next few days time.
There's nothing stopping you from running it countless times. But what will trip you up is running into the "you must restart the system and try again" type message and watch as nothing happens! Had to go through that enough times! So you have to play things by ear rather expect everything to work wonderfully likely due to the heavy online traffic of everyone trying at once to get 10! 14 million in the first 24hrs. should tell you that.
