During some installs, the LaunchAppAndWait function will display a window box while running a batch file, even though LAAW_OPTION_HIDDEN | LAAW_OPTION_MINIMIZED arguments are passed.
This has only been observed in WindowsXP on some machines. I develop and maintain the installs on a WinXP machine, and never see a full window box. I do see the program run on the task bar, and that is acceptable.
The install script is program block style, not object oriented.
ChangeDirectory (SUPPORTDIR);
LaunchAppAndWait ( SUPPORTDIR ^ APP , "" , LAAW_OPTION_HIDDEN | LAAW_OPTION_MINIMIZED | LAAW_OPTION_WAIT );
Anyone else see this?

Hi Ozone ..
Check this out in the help section of LaunchAppAndWait. May be thats why its causing a conflict.
Just a guess...
Specifies various options, including whether or not the setup should wait for the launched application to terminate before continuing. Pass one of the following predefined constants in this parameter. You can combine these constants by using the bitwise OR operator ( | ), with the following exceptions: you cannot combine LAAW_OPTION_NOWAIT with LAAW_OPTION_WAIT, and you cannot combine more than one of LAAW_OPTION_HIDDEN, LAAW_OPTION_MINIMIZED, and LAAW_OPTION_MAXIMIZED.
