Instaling office 2007 : Error1335.The cabinet file'Proof CAB' required for this installation is corrupt and can not be used.This could indicate a network error, an error reading from the CD-RO

This error is common with copies. Burn the disc at a low speed.

Sounds like the installation file is corrupted in some way. Suggest downloading a new installation file from scratch, which you can download here

Also make sure that you have met the min sys requirements as detailed here

hope this helps

i cant intall microsoft office 2007

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.

Installation files or cd is corrupt. you need to get another copy of the installation files or cd.

I think you have problem with  you setup package.if you tried to install through cd or dvd then first clean it with clean cloth and try to install . If this error again appears then contact adobe company with activation code or you details . Then they will provide new product

The corrupted files are linked to access first. So don't install it in the first phase. Install it in a second phase.

yor ms office 2007 cd or dump is corrupt pls try another one

What version of Windows are you using? Also, do you have Administrator permissions associated with your profile? You may need to disable antivirus software as well.
