Windows Installer Problem

[Guest Microsoft]

I have encountered a problem with Windows installer, which seems not to be

working properly. This does not allow me to install the updated version

KB893803 v2. In fact, whenever i run the file downloaded from microsoft

(WindowsInstaller-KB893803-v2-x86.exe) I get the message "Extraction failed:

Can't find the specific file."

 

Current File Version: 3.1.4000.4039

 

 

How can i correct the windows installer?

 

Thanks in advance.
