Windows directory's "Installer Folder" is too large, over 67GB!

I'm running Windows XP Pro. My windows directory has been growing to enormous proportions. One folder in particular (Installer) seems to contain most of the excessive files (67GB). Most are of the file types .msp and .msi. and seem to all be related to MS Office 2003!  I believe most to be unnecessary duplicate files (even though the file names are different) because dozens and dozens of the files are the exact same size. I will say that, for a long time now, my security updates for Office2003 have failed to update. Does anyone have any experience with this? Why would this happen?

This is what should clear a lot of temporary installation files.
as for the fact that the updates keep failing can you supply some kind of error etc from windows update..?

Office 2003 and 2007 have been having an issue with failed updates.
The best advice that I can give would be to disable the auto-update on Office until you know for a fact that Microsoft has the issue resolved.

The files in that area, do as p1339 has suggested.
Mine is only 763mb in size.
You should not have let it go on as long as it has.

Disable Office Auto-Update.

Good Luck

I was looking around for information and came across this, I will keep looking for more information, but you can delete it the way it says below or try and use the Microsoft Installer Cleanup utility.

MS Cleanup Utility:

23.4 GB of these files are from MS Office Update. When Office gets updated the installer puts these files here so you can uninstall the updates later, and also keeps track of what updates have already been installed.

I haven't been able to find a documented cause or fix anywhere. We can delete them, the downside of which is that you won't be able to uninstall MS Office using Add and Remove Programs, and may not be able to install Office service packs. And the downside of keeping them is that you are out of hard drive space. Doing so won't delete Office, it only deletes the uninstaller files. It's up to you.

To delete them you would open C:\Windows\Installer and sort the list by Type. Then highlight the "Windows Installer Patch" (MSP extension) files, and hit delete. Since this is going to free 70% of your hard drive, it would be a good idea to do a Defrag afterward.

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

I deleted most of the duplicate .msp files and .msi files.  Previously, I ran the MS Cleanup Utility, but it did not solve this problem. After deleting these files, I could not bring up Office 2003 as the error messages kept telling me that the various applications were not installed. I decided to remove what remained of Office and installed Oracle's to replace it.  I didn't want to be bothered with this problem again.  Thanks for all of your suggestions.

Let us know how you like the way Open Office is.
I know that I first tried it years ago and was not happy with it.

And as a reminder.
I told you to disable the AutoUpdate for Office.
A reinstall would have fixed the issue that you was having.
So, if you decided the Open Office does not give you what you want, and you want to go back to Microsoft Office, then remember to Disable the Auto Update.

Office 2000 - SP1 - SP3
Office 2003 - About the same I would think in SP's
2007 - sp1-sp2
2010 - no SP's as of yet.

All you would have to do is download the latest SP from the KB site and you will not have to worry about no update issue, as if you update to the latest SP for the version of Office that you are running, you will have everything that is needed.
If people understood that simple concept, then they would not be bothered with the glitches and malfunctioning and autoupdaters.

Good Luck
