Hi,
I am using INSTALLSCRIPT MSI project

I am trying to launch LaunchAppAndWait function in PatchUIAfter. All the paramters and exe works perfectly fine in OnBegin or between any dialog.
If i put the same code in PatchUIAfter InstallScript wont launch the exe(Basically LaunchAppandWait fails).

I checked all the parameters and exe is perfect. Guess this is issue with IS or known thing which i might not know.

Please suggest me is there any function available in installscript which can wait until my exe finishes its work other than LaunchAppandWait. I tried with Shell32.ShellExecuteA and it works fine but it wont wait until my exe is finished its work. Or can i make some how ShellExecuteA to wait in installscript to wait some how?

Need help in this
Regards

Sarfu,


Check this below mentioned function
LaunchAppAndWait ( szProgram, szCmdLine, nOptions );

in nOptions use LAAW_OPTION_WAIT....

I did tried all the parameters.
guess its a bug with IS script. Now m launching from command line cmd and pass exe as parameter.

Thanks for the help

Well, I can think of two solutions:

1) use the ShellExceuteEx + WaitForSingleObject in a custom DLL function.

2) I have not tried this but it might work, Use ShellExecute with Start APPNAME /wait
