Every time I opened Outlook I was always getting the annoying message "Window Installer, Preparing to install". In the registry I removed the add-ins of Outlook at the following registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins]. They were 3 and I removed all of them and It works. Thank you very much for the recipe.

I downloaded and installed a software from microsoft "Windows Install Clean Up". As others have written, this software removed in incomplete and corrupted installation I must have had. I removed all installers using the program and my "windows Installer" "Preparing to Install" error is gone. Finally!!! Thank you everyone for posting solutions.

For all those having this issue with office 2007, despite the fact that you use Windows Install Clean Up and reinstall office several times, here is a clean solution.

Before finding this answer, I had solved Word & powerpoint issues by fixing manually the registry (permission rights on HKCR/.pip) but I was still struggling with Excel and the stdole32.tlb message.

I used Process Monitor without any success (great tool that I highly recommend anyway: http://technet.microsoft.com/en-us/sysinternals/default.aspx).

The script given by kimwind fixed it straight away (after 10 minutes execution, be patient, it is worthy and do not worry about the few registry entries that cannot be changed).

Good luck and thank you Kimwind!

fixed the problem. open regedit goto HKEY_CLASSES_ROOT\.pip\ and change the permissions
SYSTEMS = Full COntrol
ADMINISTRATORS = Full Control
Everyone = Read

This one worked.

To fix the problem;

"Windows Installer Preparing to Install" do the following;

Start - Run - type "services.msc"

Scroll down to Windows installer and double click on Windows installer.

This brings up "Windows installer properties" change from "Manual" to "Disable", for the "Path to executable:" and apply.

Restart computer.

No more annoying errors, finally!!!

After windows repair, if you get the "Windows Installer Preparing to Install" window in every action you take, the following is really works!!!
[the thing that i couldn't get is: repairing is why so difficult? how can an end-user do these kind of things? this OS really sucks!]

Start - Run - type "services.msc"

Scroll down to Windows installer and double click on Windows installer.

This brings up "Windows installer properties" change from "Manual" to "Disable", for the "Path to executable:" and apply.

Restart computer.

No more annoying errors, finally!!! [again hate the windows whatever OS]

I just finished downloading Maplestory, but now it has said "Preparing to install..." for 20 minuetes.

The Windows Install Clean Up utility (search for that on the MS website under the knowledge base) did the trick for me.
