Extract files from a MSI
This post has nothing to do with operations manager but you will find it useful if you ever need to install hotfixes on a windows server 2008 core installation.
Here’s the situation. I needed to install some hotfixes (for SCOM but also for Hyper-V) on a windows server 2008 core environment. When you download the hotfix, and try to install it with the delivered .msi (through commandline) you will get the following notification:
Unfortunately, .NET framework won’t work on a core installation so you will need to extract the files first.
In your command prompt, use the following command:
msiexec /a PathToMSIFile /qb TARGETDIR=DirectoryToExtractTo
Example:
msiexec /a c:\hotfixes\KB954049 /qb TARGETDIR=”c:\hotfixes”
This will give you the necessary files extracted and now you can start the hotfix by starting the .msp file that you will find under the extracted directory
Cheers,
