Blindwrite bwa builder

I read a guide here on this board on how to make a bwa file with blindwrite. I currently have blindwrite5 and it doesnt have an option for bwa builder nor is it in the install folder. I am running a trial version of bw5 but where can i get a version that has this feature?

It is build in. It will make Topology if it is needed

Ok thx I tried running it once and the topology bar semmed to stop and not progress after half way through is that normal it sat there for like 10 min then i just canceled the copy. Should i wait it out?
