[WiX-users] Controling features installed with custom actions C#

[William Prada]

Hello,

 

I would like to use a custom action to read a license file and base the
installed features on its contents.

 

I have a custom action written in C# that successfully inserts a new
entry into the Property table:

 

using (View propertyView = session.Database.OpenView("SELECT * FROM
Property"))

{

    Record propertyRec = new Record(2);

    propertyRec[1] = "PRODUCT_VER";

    propertyRec[2] = "XYZ_VER";

    propertyView.Modify(ViewModifyMode.InsertTemporary, propertyRec);

}

 

In my Product.wxs file I have this to specify the custom action and when
it is executed:

 

    <CustomAction Id="CASetProductVer" BinaryKey="SupportCAs"
DllEntry="SetProductVer" Execute="immediate" />

    <InstallExecuteSequence>

      <Custom Action="CASetProductVer" Before="InstallFiles"/>

    </InstallExecuteSequence>

 

And finally, I only want to install the XYZ version of the product when
Property PRODUCT_VER=XYZ_VER:

 

    <CustomAction Id="CASetProductVer" BinaryKey="SupportCAs"
DllEntry="SetProductVer" Execute="immediate" />

    <InstallExecuteSequence>

      <Custom Action="CASetProductVer" Before="InstallFiles"/>

    </InstallExecuteSequence>

 

 

    <Feature Id="XYZVer" Title="Product XYZ Ver" Level="1">

      <Condition Level="0">CData<![CDATA[PRODUCT_VER<>"XYZ_VER]]>
"</Condition>

      <ComponentRef Id="XYZ_VER_REF"/>

    </Feature>

 

My thought was that by setting the value of Property PRODUCT_VER during
the custom action to anything other than XYZ_VER would cause the install
level of Feature XYZ to 0 and prevent its installation.

 

I have tried various ways of expressing the inside text of the condition
element but cannot prevent the installation of Feature XYZ_VER.

 

I'd appreciate any guidance you could give on this.

 

Best,

Bill Prada
