A small update is like a minor upgrade except that it's usually smaller in scope. You might use it when only a few files have changed and you don't intend to change the Product's version number.
The steps to create it are mostly the same as when creating a minor upgrade patch.
Create a new WiX project with the modified files. Do not change the
Productelement'sIdorVersion.Build the old and new versions of the product, storing the
.wixpdbfiles that get created.Create a patch
.wxsfile that defines the contents of the patch.From the command line, build the
.wxsfile with Candle and link it with Light to produce a.wixmspfile.Use Torch to generate a
.wixmstfile of the differences between the old and new.wixpdbfiles.Use Pyro to merge the
.wixmspand.wixmstfiles to create an.mspfile.
This gives you a patch file that when used will update files, but won't change the software's ProductCode or version.
