Using InstallShield 6.1

If the install is a first time install, I need to run a FoxPro EXE to do some file manipulation at the end of the install.

In OnFirstUIafter

szCommand=TARGETDIR+"\\fixtables.exe";
SprintfBox (INFORMATION, "First Install",
"Existing data must be upgraded - the FixTables program will now start",
"", svResult, nvResult, nResult );
ChangeDirectory (szPath);
LaunchApp (szCommand, szCmdLine);
SprintfBox (INFORMATION, "First Install",
"Press OK when FixTables program has completed",
"", svResult, nvResult, nResult );

However, when fixtables.exe runs, it does a MESSAGEBOX() to indicate its start and end, and these boxes tend to get hidden under the InstallSheild windows, so the user cannot see them in order to press OK.
