[wix-users] Avoid removing files (of a shared msm) by uninstalling msi

[Mike Henseler]

try applying this transform (.xsl) against the .wxs that you want to create by heat(harvest).
Works for me but you may need to refine it for your needs.

Note: this is not to be confused with a msi/mst transform 

<xsl:stylesheet version="1.0"
            xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
            xmlns:msxsl="urn:schemas-microsoft-com:xslt"
            xmlns:wix="http://schemas.microsoft.com/wix/2006/wi" >

    <xsl:output method="xml" indent="yes" />

    
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
 
    <xsl:template match="wix:Component">
    <xsl:copy>   
      <xsl:attribute name="SharedDllRefCount">yes</xsl:attribute>   
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

You will probably have to create an xml transform, to update the xml created by the heat tool.
I don't have time right now to explain or try your scenario, but wanted to make the suggestion.

Make sure your Component/@Guid is stable. The Windows Installer reference counts Components by their Guid: https://robmensching.com/blog/posts/2003/10/18/component-rules-101/

Subject: [wix-users] Avoid removing files (of a shared msm) by uninstalling msi

Hello Wix-users,

I will try my first post in this mailing list.

I am working with Wix3.11, Visual Studio 2019 and the Wixproj-Templates of VS2019.
I created a merge module with harvesting (!) its files.
I created a msi to install the merge module. Everything works fine.

I want to use the merge module with different msi's.
Now: the files of the merge module will be uninstalled when uninstalling the first msi (containing this msm)

My question:
In other case I work with Component at SharedDllRefCount="yes".
It is working fine with single files.
But here I am harvesting the source files.
Is it possible to set the value SharedDllRefCount="yes"
during harvesting to each component?
If yes (=possible),
how is the notation of coding it in Wixproj-Templates? (snippet)

What would be a practice to avoid uninstall the files in my use case?
until I uninstall the last msi (containing this msm).
I is not possible to put the files
of the msm into an own msi (because of the development history...)


Any idea?
Thanks in advance
Have a nice day

OZ

BTW - how does the search in the list's archive work?
I get diplayed the number of hits of a keyword in my browser, but no links are shown. How to get the results?
