MS Office 97 Uninstall

While I’m trying to Uninstall MS Office 97 from one of my client’s Win95 computer it gives and error (Setup Error 797) then it list few lines and says object 1877, 1881,etc

There is a message below the error: Your setup file may be damaged.

I’m trying to remove MS Office to re-install it to solve some error is MS Access.

Thanks
