A-Squared - manual update possible ?

Every so often my firewall gets stupid and won't allow A-Squared to update no matter how many times I tell firewall to allow said app, and change "Ask" to "Allow" for A-Squared's ability to access the 'net; the firewall changes it back to "Ask," after I keep clicking Yes-Allow, and click "remember the answer, and don't ask again"...

I still like old, sometimes cranky firewall (Sygate Pro, 5.5 build 2577) and don't want to retrain the PC and myself to a new f'wall, if i don't have to; I also am not keen about having to reinstall this firewall, whenever this same problem arises, so...

Is it at all possible to manually update A-Squared, like TrojanHunter, or a few similar apps - so as to bypass mystery problem w/firewall, in this case?

 

A-Squared has been having update issues lately.
Manual update produces an error message.It's been reported to emsisoft.
There is a new setup file that fixes it.
