Hi

I would like to add custom form to installation proccess. The user should point me to directory where data will be stored.

So I need textbox and button which will give the possibility to choose directory.

There is no such a form available in user interface dialog.

E.

Is this an extra dialog? There is already one that lets the user choose the primary installation folder - do you want another one?

In any event, that list of dialogs is the list of ones you can add. Visual Studio doesn't let you create your own custom dialogs for the UI sequence. I'll also point out that it won't help to do this in a custom action because they run when the install is nearly finished, and so it's too late to choose an installation folder for something.

It is not an application folder. It is folder wheredata that will be created for user will be kept. There is no dialog defined where I could use button for chosin directory.

That's true, but that's the way most installations work anyway. It's unusual to have a setup that lets you choose the primary application folder and then choose yet another folder where data will be stored. It's fairly normal to choose a profile folder, you'd do this by using Add Special Folder in the File System View, choosing User's Application Data Folder, and installing the files there (assuming you're actually installing something). Or ask the user when the app first runs.Or just store them in a profile folder anyway. If you really want to do this in the installation then you need to use one of other tools that build MSI setups and DO let you design your own dialogs because Visual Studio doesn't let you do that. It's not designed to do the same as the fully featured products from InstallShield, Wise, Advanced Installer, Wix and so on.
