Hello,
I was trying to install MS Office 2007 on a Vista Operating System.
I received the same message "Setup cannot find Excel.en-us\ExcelLR.cab..."
I canceled out of the Microsoft Office Setup.
#1 - Then I right-clicked on the very small Windows Defender icon (lower
right portion of the screen) and clicked on exit.
A Windows Defender dialog box will pop up - Asking:
Are you sure you want to exit Windows Defender?
Click Yes (Windows Defender will be active again on as soon as you restart
your computer)
#2 - Right-Click on the very small Norton Internet Security icon (located
lower right portion of the screen)
Click on Disable Antivirus Auto-Protect
A Norton Internet Security dialog box will pop up
Select - Until System Restart
Click OK
Now try installing MS Office 2007.
Special Note - When I installed my MS Office 2007, there were times I
thought the computer froze up. I gave it about 5 minutes or so, then finished
the installation successfully.
(Remember to restart you computer as soon as you have successfully installed
the MS Office 2007 software.)
