Summary:
I'm struggling to figure out the WiX code and MSI parameters to alter
installed features from the command line.
Details:
I have a WiX-generated MSI with two features, let's call them FeatureA
and FeatureB. I install from a bootstrapper which passes a command-line
parameter indicating which product(s) to install. For example, the WiX
code for FeatureA might be:
<Feature Id="FeatureA" Title="Blah Blah Blah" Level="1">
<Condition Level="0">NOT INSTALLFEATUREA</Condition>
<ComponentGroupRef Id="...
and the C# code to launch the MIS might be:
Process lExe = new Process();
try
{
lExe.StartInfo.FileName = "foo.msi";
lExe.StartInfo.Arguments = "INSTALLFEATUREA=1 /passive";
lExe.StartInfo.Verb = "Open";
lExe.StartInfo.CreateNoWindow = true;
lExe.Start();
}
(The argument string here is hardcoded, but in actuality the arguments
are built up in the bootstrapper. Arguments is hardcoded here for
simplicity.)
What I want to do now is allow the user to change which feature(s) are
installed, but I'm not sure how (for example) to tell WiX/MSI to remove
FeatureA from the command line, and add FeatureB.
Sorry if the answer is obvious, but I've been barking up the wrong tree
for the past hours and am crying "Uncle" on this one.
Thanks!
