Hi everyone,
I try to create an msp-patch to 2 msi-packages with msimsp. I create the pcp with WiX. I found out that my patch works well when I have an external, uncompressed cab-file to each msi-package.

In my case it is necessary to compress the cab since the file gets too large:
uncompressed: more than 500MB
compressed: about 128MB
When I do this, I cant create the msp and get an error:
"PatchWiz is unable to patch files compressed in a cabinet."

How can I make a patch out of two msi's that have an internal compressed cab file?
If this is not possible - how can I extract and uncompress the cab of an msi (in a batch for example)?

Thank you,
Chris

Hello,

create an administrative installation ( msiexec /a ...) for all compressed MSIs and use these installations as sources of the patch.

How to perform an administrative install is written in the docs and also hinted in Johannes' post.
