TRYING TO LOAD MICROSOFT OFFICE 2007 ONTO MY LAPTOP WITH (WINDOWS XP) HALFWAY THROUGH THE LOADING THE MESSAGE 'SETUP CANNOT FIND ENTERPRISE.WW\ENTER WW.CAB. BROWSE TO A VALID INSTALLATION SOURCE AND THEN CLICK OK' POPS UP. HOW DO I FIND THE INSTALLATION SOURCE. I HAVE DELETED ALL OTHER PRE-INSTALLED MICROSOFT OFFICE PROGRAMMES. WHICH WEBSITE CAN I DOWNLOAD THE ENTERPRISE.CAB PROGRAMME FROM IF I NEED TO DO THAT?

PROBLEM WITH THE C DRIVE INSTALL THE OPERATING SYSTEM ONCE AGAIN AND TRY.
OR TRY TO INSTALL IN ANOTHER DRIVE LIKE D OR E DRIVE.

Here are some good solutions: http://www.fixya.com/support/t6138262-setup_cannot_find

Either repair the installation or just uninstall and reinstall it.

I'm assuming that you bought it legally. The source of the installer is corrupted. Either get it directly from another source
http://www.brothersoft.com/microsoft-office-60484.html
or just get rid of it and install and use Open Office
http://www.openoffice.org/

Is this Licensed version you are trying to install from ? Contact Microsoft regarding this Issue.

If not, you will have to try with different Copy of the Office installation Disk since the disk you are using has the CAB file ( cabinet file ) missing.

Is this being installed over a network. If so try installing it on the local machine and not over the network.

Setup cannot find Enterprise.WW EnterWW.cab. Browse to a valid installation source, and then click ok

Based on my experience there are many reasons that this issue may occur. I
suggest you try the following suggestions:

* Suggestion 1: Clear Temp folders
======================
1. Click Start>Programs>Accessories>Disk Cleanup
2. Clear your Temporary Internet files and temp files.
3. Restart the PC.
4. Copy your Office 2007 files and folders to a local folder.
5. Double click on the Setup.exe to start the install process.

* Suggestion 2: Check the Environment Variables
====================
I remember I have resolved some similar issues that the users report Office
2007 has failed to install. I have figured out this is caused by the wrong
configuration of the user variables. To check it, please follow the steps
below:

1. Right click on Computer, and choose Properties
2. In the Tasks list that appears on the left, click Advanced system
settings.
3. Click Advanced tab, click Environment Variables.
4. Under User variables for user name, check if TEMP is configured as the
following value: "%USERPROFILE%\AppData\Local\Temp"

* Suggestion 3: Install under Vista safe mode
======================
Please try to install Office 2007 under Vista safe mode:

1. Restart Windows.
2. At the boot sequence, long press F8 key to invoke startup menu.
3. Choose Safe Mode with network connection on the menu and press Enter.
4. After Windows starts in this mode, install Office 2007 again and see the
result.

It sounds like the disk is damaged, try downloading Office Professional from microsoft website and using the product key supplied with your disk

you can skip the dll file during installation. go to windows or microsoft update from your desktop and download the patches. it should fix the problem you have.
you probably have about 12-16 patches.
