asked on

locate .exe on remote PC

I need to query our network and determine which machines have certain apps installed.

I was hoping to have powershell read from a CSV with netbios names and output a list of PCs that have the exe on them.

What would a script like that look like?

Do you know where the exe file will be? Searching an entire file system is quite time-consuming, even if we went down the remoting road and had the client system do it for you.

This will scan your pc's and list all installed apps

hope you don't mind it's vbs.

the script ping first to check availability, then query installed apps on registry and log each program for each machine if installed or not.

it reads he machine list from a file (c:\temp\machines.txt)
the apps list are hardcoded but can be also read from a file.

i was checking 2 applications Safari & Windows Live Essentials, so the output log should be something like this.

Windows Live Essentials could not be found
