We have an installer that has been working fine with auto-upgrading. However about 10 days ago a rebuild of the exact same installer project is now producing an exception "The specified account already exists". This is happening just as it is going to begin the new install after uninstalling the previous version. That leaves our software uninstalled.
Screenshot is attached.
I am sending our zipped project file to support at AI.
Thank you very much for your time.
