Current AI has a feature to create a virtual directory, it works fine except if there is already a virtual directory there. The installer will error out.
I think many people have similar cases like mine. I have several web applications in IIS already, I definitely do not want to override the setting of my virtual directories (for example, certificate settings) when I run an installer, but I do not like the installer error out either. I guess maybe there is a way to have optional settings, like to create a virtual directory if there is none there.
Because of the case, now I have to write vbscript with custom actions.
Hopefully this will be handled properly in future releases of AI.
Thanks!
