KB911562: /nobackup switch doesn't work

[Tomcat76]

Both the dialog you get after running this hotfix with the /? switch as well as the relevant KB article page explain that the /nobackup switch should be used to skip making a backup. This is the full install string I'm using:

KB911562.EXE /quiet /norestart /nobackup

That's done after the first logon (not at T-13). The hotfix installs properly, but the uninstall folder is created in C:\WINNT and Add/Remove Programs contains an entry for this hotfix (though it cannot be uninstalled from there).

Is there any way around this other than using a batch file that removes the uninstall folder and the relevant registry value for the entry in Add/Remove Programs post installation?
