Uninstaller error message when dir is not empty

[brunobastosg]

Suppose my application installs to a folder called myApp.

Inside myApp there are several files and folders.

After a run my application for the first time, it creates a folder called appData.

I inserted a Remove From Uninstall action so the appData folder is ignored during uninstall.

The problem is the uninstaller tries to remove the <%InstallDir%> folder (myApp).

I need to tell InstallJammer NOT to remove the myApp folder IF there is a folder called appData.

I tried inserting a Remove From Uninstall action with a Directory Exists condition, so the myApp folder is not removed if there is a folder called appData.

But doing so causes InstallJammer to remove the appData folder and all its files and directories from the uninstall, so nothing gets uninstalled.

I need InstallJammer to try to uninstall everything it is supposed to, with the exception of the myApp folder, so it doesn't show the "Dir ... is not empty" message.
