Add missing file with msp patch

Question

I created an installer, deployed to our test environment and got an error due to a missing dll (it was not included in the wsx file). Is it possible to create a MSP patch to shi

Answer 1

Yes, you can add a missing file through a patch. Perhaps this article will help: http://wix.sourceforge.net/manual-wix2/patch_building.htm

When creating a patch you should always modify your existing installer. You don't create a new installer from scratch. Also, never remove resources from the new version. For a patch you should either modify or add resources.

Regarding error 2356, it seems like the original installation is somehow corrupted. You can try repairing the old version before applying the patch on it.
