Launch an Application

[heko_76]

I am using Installshield professional 2008 .I want to install an exe which is will come in the custom option of the setup type.

I wrote the neccessary code in the Program_installed event
The PROGRAM is pointing to a exe on the local file system.


function Program_Installed()
NUMBER nWait;
begin

//if (LaunchAppAndWait (PROGRAM, "", nWait) < 0) then
if (LaunchApp (PROGRAM,"") < 0) then
MessageBox ("Unable to launch "+ PROGRAM +".",SEVERE);
endif;
end;
But it always gives me an error. says cannot launch exe.Please help asap

Hi,

First of all check that the file exists. Even if your 100% sure it does, it's always a good check to make!

nReturn = Is( FILE_EXISTS, sYourProgram );
MessageBox( "File Exist returns: " + FormatMessage( nReturn ), WARNING );
if ( nReturn = 1 ) then
  nReturn = LaunchAppAndWait( sYourProgram, "", LAAW_OPTION_WAIT );
  MessageBox( "LaunchAppAndWait returns: " + FormatMessage( nReturn ), WARNING );
endif;

FormatMessage() will turn the return value into a string telling you what a function returned. I personally don't use it as I use the debugger, but it might help you!

Where abouts are you calling this bit of code? Are you certain it's called AFTER the file has been installed?

Let us know what the two calls return!
