Dear community,
I want to create a Patch (MSP) for an existing MSI Setup package. Therefore
I use the "diff" between my currently released MSI and the new one I
have/want to create. I understand how to update existing components of my
initial MSI package, but how can I add new files or remove complete
components from the old installation?
Here is my current WiX patch code ("patch.wixmsp"):
---------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi";>
<Patch
AllowRemoval="yes"
Manufacturer="My Company"
MoreInfoURL="http://www.my-company.com/";
DisplayName="My Product 1.0 Patch 01"
Description="Small Update patching the My Product Version 1.0.0 to
1.0.1"
Classification="Update">
<Media Id="5000" Cabinet="RTM.cab">
<PatchBaseline Id="RTM"/>
</Media>
<PatchFamilyRef Id="MyProductPatchFamily"/>
</Patch>
<Fragment>
<PatchFamily Id='MyProductPatchFamily' Version='1.0.0' Supersede='yes'>
<!-- Update of existing components: BEGIN -->
<ComponentRef Id="PatchThis1.dll"/>
<ComponentRef Id="PatchThis2.dll"/>
<!-- Update of existing components: END -->
</PatchFamily>
</Fragment>
</Wix>
---------------------------------------------------------------------------------------------
Do I have to add the new components to the <PatchFamily> section directly or
add it in my 1.0.1 MSI?
How can mark the components as "to be removed"? Do I have to change my
original MSI therefore?
Here goes the build script for the current "patch.wixmsp":
---------------------------------------------------------------------------------------------
echo.
echo - Generating difference between MSIs...
echo.
"%WIX%\bin\torch.exe" -p -xi "current\My Product.wixpdb" "update\My
Product.wixpdb" -out "_build\diff.wixmst"
if ERRORLEVEL 1 goto error
echo.
echo - Compiling...
echo.
"%WIX%\bin\candle.exe" -out "_build\patch.wixobj" "patch01.wxs"
if ERRORLEVEL 1 goto error
echo.

if ERRORLEVEL 1 goto error
echo.
echo - Building patch...
echo.
"%WIX%\bin\pyro.exe" "_build\patch.wixmsp" -out "My Product 1.0 Patch
01.msp" -t RTM "_build\diff.wixmst"
if ERRORLEVEL 1 goto error
goto end
:error
echo.
echo - Build failed!
pause
exit /B 1
:end
echo.
echo - Build completed successfully.
pause
---------------------------------------------------------------------------------------------
Many thanks in advance!
