Is anyone having as much trouble with LaunchAppAndWait as I am - I cannot get the function to work. The program does not launch. The code I am using is:

GetCurrentDir( szCurDir );
ChangeDirectory (szPathDB);

LaunchAppAndWait("InstallDB.exe",szCmd2,LAAW_OPTION_WAIT);

// Restore the old working directory:-
ChangeDirectory ( szCurDir );

Where:
szPathDB = szBuildDBRoot + "\\InstallDB\\Bin";
szCmd1 = "1/" + @CATALOG + "/" + szServer;
szCmd2 = "2/" + @CATALOG + "/" + szServer;

szBuildDBRoot is the Drive letter of the source media.

Any thoughts? I am at wits end on this one.

Use full path?:

EXEPath = "\"" + INSTALLDIR ^ "TheExe.exe" + "\"";
LaunchAppAndWait( EXEPath, "/option", WAIT);

I have also used the full path without success. I modified the code to change the directory at the suggestion of another user. I have also tested the program that is launched to make sure it was not the source of the problem.

Did you add quotes at each end of the path using "\"" ?:

EXEPath = "\"" + INSTALLDIR ^ "TheExe.exe" + "\"";

I am running the executable file from the CD Drive. Is it possible that running the program from the CD Drive is causing the problem?

Hi,
maybe that by adding LAAW_OPTION_NO_CHANGEDIRECTORY
to the LaunchAppAndWait function.
instead of LaunchAppAndWait("InstallDB.exe",szCmd2,LAAW_OPTION_WAIT); try:
LaunchAppAndWait("InstallDB.exe",szCmd2,LAAW_OPTION_WAIT | LAAW_OPTION_NO_CHANGEDIRECTORY);
