Checking the Version of Windows Installer
One of the requirements of upgrading to Microsoft Operations Manager 2005 SP1 for you clients is to ensure those clients reporting to MOM are running Windows Installer 3.1 or higher. After attempting to install the agent on my Integration servers I noticed that large amount of them did not have that version. It sure would have been nice to have known which version they were running. I found such a way but it is only run on one server at a time. Just log on to that machine and from the Run dialog box just type msiexec.exe /?.
Any scripting people out that know a better way please let me know. I really need to make that a focus of mine...scripting.
Also if you need to download the latest version of Windows Installer just check here.
