How can I script Adobe Reader updates using vbScript, PowerShell or C#?

I would like to script Adobe Reader updates using vbScript, PowerShell or C#, are there any Adobe API calls I use to do this.  There are several different version that I support and auto update is not an option. I do updates at a specific time of the month. I would like to write a script that would download and install the update for the currently installed version of Adobe Reader (32 or 64 bit) for the version of the OS (32 or 64bit). I can detect the OS version and the Adobe version.  I can download updates but I do not want to hard code anything
