No it is not necessary to mark it as permanent. If its a vendor MSI, you should restrain from marking it as shared if its permanent and vice-versa.
If it is known that the particular component is shared by many applications than you should mark it as Shared. Else if its a custom DLL or any other file, not to be shared, than it can be marked as permanent.

suppose if we mark a component (installing file to system32) as shared then during uninstall will it be removed or left behind ? - yogesh101 12 years ago

It`ll be left behind....it is because other applications may need it. - akki 12 years ago

yeah it should be left behind......but r u sure abt it?
bcos I checked the same & found tat it does not.....
after installing my app added some files in sys32 and even
if they were marked shared, on uninstallation they were removed..?? - yogesh101 12 years ago-
Did you check if "Always increment shared .Dll count" is checked or not in ur database.
This count increments on every install and decrements on uninstallation. If the count becomes zero the shared component will be then uninstalled. - akki 12 years ago

yes it was checked........but since I tested on a clean build and since my app installed
the file so during uninstallation as u said the count must have become zero and it got removed since no other application is using it.......anywaz thanks for the useful info :) - yogesh101 12 years ago -

Yes you can mark as a shared.
Or you can mark permanent, common files and mark shared, application specific files.
