Launching msi when we try to open word document

[sandeep.madhu14]

When we try to open any word document it is launching MSI by giving message that Configuring msi.




Every time I try to run any Microsoft Office program, simultaneous with the splash screen, a Windows Installer window shows up and says "Preparing to install..." .This then brings up another installation window saying "The feature you are trying to use is on a network that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'xyz.MSI' in the box below" [The box below is a browse field.]


we are not able to find why it is launching msi when we try to open word.any suggestions would be great.
