I have .bat file that I call from LaunchAppAndWait() withWAIT option seelcted and .bat gets called and works fine when I debug the install script. The same code does not work when I run the setup.exe. but I dont get te failure message.

//dbinit.sql
svpcmd = svMpsHome ^ "\\MySQL\\mysqlInstall.bat";
svpline= "";
nOptions = LAAW_OPTION_WAIT | LAAW_OPTION_HIDDEN;

if (LaunchAppAndWait ( svpcmd, svpline, nOptions ) < 0) then
SprintfBox(WARNING,"Failed to run dbinit.sql %s", svpcmd);
endif;

Maybe your batch runs (insert a Pause message, or remove the hidden flag for testing) but maybe it doesn't work right. Are you relying on the current working directory in your .bat? You should use full paths instead.

One thing that I've done to debug situations like this is to pipe the output from the batch script to a txt file... assuming there is output in the batch file.

CODE

szProgram = "cmd"
szOptions = "/C " + svMpsHome ^ "\\MySQL\\mysqlInstall.bat >> C:\outputfile.txt 2>&1";

nReturn = LaunchAppAndWait(szProgram, LAAW_OPTION_WAIT | LAAW_OPTION_HIDDEN, szOptions);

Riddle your batch script with "echo"s.

Oh, and see what nReturn really is after.

Hope that helps.

when I add echo and pause in the batch file and take out the hidden mode, it works which is not acceptable as we dont want to see a cmd window during install.

but when i remove the echos and pause and do it in hidden mode it is not working. very strange.
