Hello,

Getting the above error when I attempt to remove the office 2007 installation. I am repairing because when I start to run any of the office 2007 software, windows installer dialog box appears. Nothing happens for a very long time so I click on the cancel button.

When I do Office 2007 repair, after a while the error msg is ...Error 1304:Error writing to c:\program files\common files\microsoft shared\office12\mso.dll. Verify that you have access to the directory. The mso.dll file is located in the directory. This error only started happening from this morning. Everything was fine yesterday.

Don't want to uninstall then reinstall Office 2007.

many thanks.

Hello,
It sounds like the local installation cache may be corrupted.

Are you working with full admin rights on the computer?  Limited rights will give problems when editing anything in program files.

Is this XP or Vista?  How was 2007 installed to begin with (DVD, preloaded, something else)?  If it was through DVD, just reinstall without uninstalling.  
Good luck!

Hello,
Thanks for the reply. It was full rights on the computer. OS is WinXP Pro SP2. Office 2007 Pro was originally installed from the CD. I was upgrading from Office 2002 to 2007.
I tried reinstalling without uninstalling, but this did not work. Still got Error 1304. So I uninstalled Office 2007 and reinstalled it. Everything works fine now. Still do not understand what went wrong.

Rdgs,

It's tough to say exactly what went wrong exactly.

Office 2007 changed a lot of installation routines and processes.  I think the 2007 suite is still new enough that solutions are not readily available online.  
Chances are sometime during your upgrade from XP, a file was not properly copied or created, and therefore, this corrupted the local installation cache which Office uses for feature adding/removing and Detect&Repair.  Just a guess..
Glad you got it working!

Glad you have it working!
