What is a MSI file (needed for rescue cd)?

[BarronN30]

Hello, I'm trying to create a rescue cd just in case one day I need to use it to delete some viruses.
I downloaded Windows AIK and I got all the way up to where you choose 3 options to put the rescue in.
I want to burn it to a DVD and in the options it asks for a MSI file. I googled and searched this forum and I can't seem to find what it is.
Which file am I suppose to target?

I believe it's referring to the antivirus installer....

ex...

The ESET NOD32 Antivirus 4 installer is eav_nt32_enu.msi

See if this KB article helps...

Ohh I see. It didn't detect my installer cause it was 64 bit.
Thanks for the help and the link!
