Unable to update anymore

[Gringo1028]

I get the , "Launchbox is having trouble starting the setup application because it seems that another application (such as Dropbox) is using the file. Please try again or try downloading the latest version from the website to update" Message when I try to update.  I am stuck on 12.3  I am not using drop box.  Is there a manual update I can use?  Thanks

I have had the same issue with the last 2 updates, it is very frustrating.

What I did was download the new release, install it and then move the Launchbox executables to the old versions.  Seems to work, but it is not as seamless as before.
