Hi All,

Having noticed an MSI file containing only several registry components (~50) was almost 1 MB, I did some research on how size can be reduced. I found this article http://www.symantec.com/connect/blogs/reducing-size-msi-file and followed the steps as suggested.

Basically, I opened the MSI in ORCA, exported all the data tables to .idt's, created a new MSI in ORCA and imported all the tables.

I checked the size of the new MSI, however, it wasn't any smaller (I think it may have been a few KB larger). Did I miss a step or would this mostly apply to MSIs containing several items stored in the binary table?

Trying to squeeze a lot of data into a DVD for deployment. Currently without MSI, we are hitting the ceiling.

So you have a 4.7gb DVD and are worrying about a 1mb MSI file?!

If your package is just registry entries and if space is really that tight, why not use a ZIPped .REG file, plus a script to unzip and merge the .REG?

Hey VBScab - The MSIs are being deployed using a provisioning tool which also remediates machines that are online so the MSI must "self-heal." The .reg approach would work but I'd have to do an appsearch for each reg value to validate.

Hello, you might be able to shrink the files by using the free (but old) Ziff Davies unfrag.exe tool available at

This was originally intended for compound documents such as Word file etc. But as MSI files are structurally similar, it does work on these too.

(Make a backup copy of your MSI, just to be on the safe side, though)
