First of all, I think WiX is pretty awesome, but I am having some trouble
understanding how to implement some of the advanced customization/extension
capabilities, and what is the best way to design and implement ...
My new assignment wants me to modernize and cleanup a 15-year old IS6 install
that has evolved into something that is no longer sustainable and does not
support 64-bit. I've developed a BA, but my main hang-up is that the WiX
application MSI I created needs to call a license utility to get configuration
information necessary for a fresh install, writing that config info to the
Registry (I know), so we know which [mutually exclusive] camera driver to
install. What would be the best way to implement this? I see two choices - 1)
wrap the camera drivers in an exe that checks the Registry and installs the
proper camera driver, or 2) extend the BA to be able to check the Registry
during Apply(). What would be the best choice (I know there may be more than
the two I mentioned), and why? Also, if extending the BA is a possibility, what
is the best way to do that?
The simplified chain looks like this:
<Chain>
<PackageGroupRef Id="APPLY_PREREQUISITES"/>
<PackageGroupRef Id="APPLY_THE_APPLICATION_MSI_THAT_I_CREATED"/>
<PackageGroupRef Id="INSTALL_CAMERA_DRIVER"/>
</Chain>
