Hard to say without seeing models for db.application and db.version
but this may be what you're looking for:
def downloadApp():
query = db(db.userSoftware.user_id==auth.user_id) & \
db(db.userSoftware.application_id == request.args(0)
existing = db(query).count()
if not existing:
db.userSoftware.insert(user_id=auth.user_id,application_id=request.args(0))
return response.download(request,db)
