[wix-users] Patching

[Christopher Painter]

Are all your components each in their own fragment?

http://wixtoolset.org/documentation/manual/v3/patching/wix_patching.html

"A sample product is created which puts different resources into fragments. You put resources into separate fragments so that the resources in each fragment can be filtered out of a patch. You might filter some resources out of a patch if you want to limit the patch to update only parts of your product or products."



I'm not a patching expert but recently went through this whole story and got it working all the way to digitally signed patches that install/uninstall without  UAC prompts.   I'm still not sure why my customer wanted this as his MSI was only 9MB  and 30 files but so be it.  He really wanted to be able to create 30KB - 300KB  patches  even though AFAIK he's not installing to a huge amount of machines at a time.

Hi folks,

I am trying patching… I created a patch.wxs and specified just 4 binaries instead of all 11. But when creating the patch it stuff all the binaries in the patch…
Using WiX 3.11.1 and use melt/torch/candle/light/pyro to create the patch:

Used info from:
https://www.firegiant.com/wix/tutorial/upgrades-and-modularization/patchwork/
Patchwork - WiX Experts and Resources from FireGiant<https://www.firegiant.com/wix/tutorial/upgrades-and-modularization/patchwork/>

Patchwork. It wouldn't be terribly effective to create an upgrade installation package with megabytes of files in it just because one or two small files inside have to be renewed.

      <ComponentRef Id="cmp_two.dll"/>
      <ComponentRef Id="cmp_three.dll"/>
    </PatchFamily>
  </Patch>
</Wix>

Used this script to create patch:

set INTERMEDIATE_DIRECTORY=D:\SomePath\Installation\Patch
set OLD_INSTALLER=%INTERMEDIATE_DIRECTORY%\MyProduct\old\bin\Release\en-US
set NEW_INSTALLER=%INTERMEDIATE_DIRECTORY%\MyProduct\new\bin\Release\en-US

rem old and new folders has the “old/new” versions of the .MSI and .wixpdb files

rem Use melt.exe to create a better .wixpdb: https://www.joyofsetup.com/2013/07/16/easy-pure-wix-patching-with-melt/
call "C:\SomePath\WiX\3.11.1\Melt.exe" -v %OLD_INSTALLER%\MyProduct.msi -out %INTERMEDIATE_DIRECTORY%\MyProduct.Old.corrected.wixpdb -pdb %OLD_INSTALLER%\MyProduct.wixpdb -x %INTERMEDIATE_DIRECTORY%\ProductOldbits
call "C:\SomePath\WiX\3.11.1\Melt.exe" -v %NEW_INSTALLER%\MyProduct.msi -out %INTERMEDIATE_DIRECTORY%\MyProduct.New.corrected.wixpdb -pdb %NEW_INSTALLER%\MyProduct.wixpdb -x %INTERMEDIATE_DIRECTORY%\ProductNewbits
call "C:\SomePath\WiX\3.11.1\torch.exe" -p -v -xi "%INTERMEDIATE_DIRECTORY%\MyProduct.Old.corrected.wixpdb" "%INTERMEDIATE_DIRECTORY%\MyProduct.New.corrected.wixpdb" -out "%INTERMEDIATE_DIRECTORY%\patch_en.wixmst"
call "C:\SomePath\WiX\3.11.1\candle.exe" -v "%INTERMEDIATE_DIRECTORY%\patch_en.wxs"
call "C:\SomePath\WiX\3.11.1\light.exe" -v "%INTERMEDIATE_DIRECTORY%\patch_en.wixobj" -out "%INTERMEDIATE_DIRECTORY%\patch_en.wixmsp"
call "C:\SomePath\WiX\3.11.1\pyro.exe" -v "%INTERMEDIATE_DIRECTORY%\patch_en.wixmsp" -out "%INTERMEDIATE_DIRECTORY%\patch_en.msp" -t media1 "%INTERMEDIATE_DIRECTORY%\patch_en.wixmst"

Any idea why it is picking up ALL the binaries instead of just the 4 that I listed in the patch_en.wxs file (yes the compentref id are the same in the new/old installer)

Thanks,

Steve
