Well, 5 or 111. That's the error I started getting today when packaging my forms into .EXEs. I'm rebooted, uninstalled/reinstalled, deleted c:usersusernameappdataroamingsapienprimalforms 2011temp, uninstalled/rebooted/reinstalled, and basically it keeps happening - but occasionally it works, to make it weirder (usually after I swap it between 32 and 64bits, sometimes when I check STA, but all of them work sometimes, none of them work all the time). My first workstation always gives the error in the title, but then I jumped the PFFs to my other workstation, and it could package them sometimes, but when it failed it gives the same message, but ends it in 111. I can't find any documentation on this error, or how to resolve it. Any ideas?
