Stuck with .msi file.

[#1]

I am trying to run a .msi in middle of installation with LaunchAndWait function but it does not seems to work.i read in installshield forum that it is possible by using LaunchAndWait and calling msiexec.exe.but i am not able to achieve it.Anybody here to help me out.:confused:

What kind of project are you using? If you're using a Basic MSI or InstallScript MSI, you may be prevented from running the LAAW because an MSI is already running.

If you're using a pure InstallScript project, please post your code.

I got the solution we have to call msiexec.exe to run the msi file.refer to this link.

Note that you can't launch a child msi from within the execute sequence of the parent msi. No 2 msi's can 'stay' in the execute sequence at the same time...
