Hi there,
I've noticed somethnig strange in a small install project I've recently created. It seems the automatic upgrade, on many machines, will fail to install the main payload of the installer, the .exe. Documentation gets installed fine. The .exe is not currently running. It uninstalls, finishes the install without error, and then when running the installed application, simply opens the installation folder, where the application is nowhere to be found. A re-run of the installer with the "repair" option selected works fine on affected systems. It seems to me that it may be actually removing the newly installed .exe during cleanup, or something.
