I actually wanted to display a status bar in the Basic MSI Project.

Basically I have two Installscript custom actions in which I am using installing two third party softwares silently using LaunchAppWait Dialog.

I have sequenced them on next click of the InstallWelcome dialog.

Now I want to show a Progress bar to indicate the progress that the installation is going on.

Now I wanted to know how can I implement the same. Also in case I decide to use the Progress bar control, how do i dynamically depending on the installation status of the softwares update the Progress Bar.

Any information would be a great help.

Also any information on updating the progress bar and how to increment progrss bar using installscript or VBScript would be appreciated.

Thanks

You need to display standard dialog SetupProcess in UI sequence. when you execute your installers you need to specify LAAW_OPTION_USE_CALLBACK option.
Then implement OnLaunchAppAndWaitCallback() event. This event will be called each 1 second by default, you can change interval as well.
In that callback you can use event send to MSI MsiProcessMessage(hMSIHandle, INSTALLMESSAGE_PROGRESS, hProgressRec); Read about this event and its parameters in Microsoft MSI help on MSDN.
