A simple EXE packaged with the Package and Deployment Wizard refuses to install on one particular machine.
Having completed the bootstrap SETUP1 complains that it cannot find ST6UNST.exe in the TEMP directory. A manual check shows the directory has been created but the file has not been copied.
If we copy the file manually before starting SETUP returns the "Some components are out of date..." message and reboots the machine. After the restart the problem starts all over again.
