The Default installation type is the quickest and is useable for demo or test installations.

It has the following limitation:

It will install the files to the default folder

It can only be installed to the Default Web Site in IIS

It will create a virtual directory FieldPortal20 depending on version selected

When doing an upgrade to a later build the IIS settings will be removed and reinstalled. This means any manual IIS configurations will be lost and will have to be redone.
