I was in search of a method to effective overwrite an existing file though my MSI. It seems windows installer is missing such a functionality as the file versioning rules don’t have a word about it. According to MSDN the file replacing is done considering properties like version, date and language.

I was playing around the MS office XP security update packs last week. These packages (exe files) can be easily and silently deployed using a /Q switch.

Ouch.. I’m on a few security updaes packs for MS Office Suite for the past 7 days. All these KB hotfixes contains MS Patch (.MSP) files for fixing some security holes in MS Office. For silently deploying these packages we can use a /Q switch on each of these update exe files.
But things are a bit different when we come to the silent removal of the updates. The Windows update packs used to have a /uninstall switch for removel. This together with /qb could do a smooth and silent uninstallation process. But this feature was missing from MS Office Hotfixes!
