Hi folks, I'm having a problem with the WixDIFxAppExtension when I'm using it in merge modules, and I'm wondering if someone can offer me a simpler workaround than what I'm currently planning on doing :)
The problem is caused when we try to build two different merge modules using WIX (v3.0.4624.0) that include drivers and then include both those merge modules in one MSI. Both merge module projects link with difxapp_<platform>.wixlib, which adds the DIFx custom actions in the merge module custom action table: MsiProcessDrivers, MsiInstallDrivers, etc. When those two merge modules are then merged into the same MSI, we obviously get duplicate row errors and the merge fails. My hope would really be that if WIX builds a merge module using WixDifxAppExtension, instead of adding the DIFx custom actions directly if it instead would add a ModuleDependency on the DIFxApp merge module. Then we could merge multiple merge modules that all depend on DIFxApp, and then the DIFxApp merge module would be merged in too to get the custom actions. But that's not what it does, so I'm looking for a workaround... One option we have is to build wixlibs instead of merge modules, but since I'm not guaranteed that consumers of our merge modules are going to use WIX (they might be using InstallShield) that doesn't really work well for our team. The other option I think I have is that instead of using WixDIFxAppExtension, I'll add a <CustomTable Id="MsiProcessDrivers">... and "manually" add the rows I need to the table, and then add the Dependency on the DIFxApp merge module too. The problem here is that every merge module we create has to add the CustomTable, and we have to go look up the column definitions again, and then we have to look up the documentation to figure out the bit values we need to set in the Flags column. I'd like a way where we get to continue to use the nice xml schema and can still merge everything successfully. I've also considered modifying the WIX DIFxAppExtension source to do what I want too... but my workaround is easy enough to do, and since I'm unfamiliar with the WIX source, I figure it's a lot faster for me to work around the problem for now. Any other ideas?
