Office 2007 Configuration wizard runs every time I start any Application (word, excel, etc)

Question

Hi!
I've installed Office 2007 Enterprise on my Vista x64 system, but when I'm
starting any of the Office apps, Office runs a setup/configuration prog
(Office is collecting/gathering setup information or something like that).
My event log has produced
numerous warnings, on of the more significant is :
Detection of product '{90120000-0030-0000-0000-0000000FF1CE}', feature
'ProductFiles', component '{6252B847-BADA-43D4-9252-E39767FA40A1}'
failed.  The resource 'HKEY_CLASSES_ROOT\.pip\' does not exist.
I tried to access the HCR\.pip\ key in Regedit and receive the
following message:
"Error Opening Key
..pip can not be opened.
An error is preventing this key from being opened.
Details: Access is denied."
I have tried the Windows Installer Clean up utility to remove all
traces of Office, cleaned the registry, reinstalled Office 2007 
4 times and still have the install/configuring messages popping up
upon loading the Office programs..
ANY information would be appreciated !!!
Thanx a lot @lby

MAZENS's WAY SOLVED IT
Thanks Mazen, nice move, it has worked out,
[The rest is for 'still-learners' like me, please follow the following :)]
Start Menu->Control Panel->AdministrativeTools->EventViewer (Hurray, we have the so called found event viewer)
Then hit 'Application', which brings
Type , Date, time, source bla bla window in which the events are listed.
I started reading them one by one. Once you hit a line (information), 'event properties ' window opens. You can see that there are arrow buttons to scroll down and up among the events. And there is the 'description' part in the same window. While scrolling thru all messages (information lines), I came across the follwing messages in the 'description' section:
The description for Event ID ( 0 ) in Source ( ServiceLayer ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: Service started.
Another event's description was:
The description for Event ID ( 0 ) in Source ( gupdate1c99657ceb0c142 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: Service stopped.  
As you may have recognized message mentions about 'Event ID ( 0 )'.
So I followed Mazen's directions and replicated ID_00030.DPC and renamed the replica as ID_00000.DPC
Now it is working without any configuration pop up. By the way, before creating ID_00000.DPC, I had already tried  ID_00011.DPC and ID_00051.DPC. Now I have four .dpc files (0,30,11,51) in C:\Program Files\Microsoft Office\Office12
As Office2007 application is starting fast now, I don't bother about them (i guess/hope it is ok).
Best wishes,
