Hazel, just for you I have downloaded CC v 3.18 (64bit)
Both CC and CP show the same 11 applications installed on 10/03/2012 when Windows was installed on my SSD.
C.P. shows 13 apps installed on 10/03/2012, when Windows was first installed.
CC shows 14 apps, 13 the same plus one duplicate :-
COMODO Internet Security COMODO Security Solutions Inc. 10/03/2012 154.0 MB 5.9.25057.2197
COMODO Internet Security COMODO Security Solutions Inc. 10/03/2012 5.9.25057.2197
C.P. shows 4 more apps dated 11/03/2012 17/05/2012 18/05/2012 18/05/2012
C.C. shows same 4 apps dated 11/03/2012 16/05/2012 17/05/2012 17/05/2012
I installed Palemoon on 18/05/2012 as shown by Control Panel
The Palemoon installer created a folder with a time stamp 18 May 2012, 16:55:01
All the files within the folder have the same creation time stamp.
The Control Panel shows the actual date of the creation of the application.
REGISTRATION of an application is a separate process from creation.
Palemoon only became my Default Browser because after creation I asked it to become my default.
Registration is part of the black magic in Windows, and probably buries the information in the registry.
CC detects installed Apps by registry entries so it probably gets the registration dates from there.
I do love a good conspiracy theory. How about :-
Every App that is installed is registered in the registry and reported back to Microsoft / C.I.A. / F.B.I.
and a U.S.A. server time stamp then appears in my registration details ![:o]()
I am using 64 bit Windows 7 Ultimate + SP1
