Is Penumbra Collection on DVD patched?

[wkduffy]

Well, the install from the DVD Penumbra Collection puts all the games in a separate folder "Penumbra Collection" (C:/Program Files/Paradox Interactive/Penumbra Collection/Overture [or] Black Plague [etc.]...). For patches, the installer says the appropriate folder does not exist (for example, for Overture it defaults to C:\Program Files\Penumbra\Episode 1) and asks if the folder should be created. Will this work? Where exactly should these patches be installed then?

Sorry to be boneheaded, but this is not entirely clear to me.
